Important Formulas – 

Operations on Real Numbers

√(a/b) = √a/√b

√ab = √a √b

(√a + √b) (√a – √b) = a – b

(a + √b) (a – √b) = a 2 – b

(√a + √b) (√c + √d) = √ac + √ad + √bc + √bd

(√a + √b) 2 = a + 2√ab + b

NCERT Solutions Class 9 Maths Chapter 2 Polynomials

This chapter discusses a particular type of algebraic expression called polynomial and the terminology related to it. Polynomial is an expression that consists of variables and coefficients involving the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables. The chapter also deals with the Remainder Theorem and the Factor Theorem with the uses of these theorems in the factorisation of polynomials. Students will be taught several examples as well as the definition of different terms like polynomials, degrees, coefficients, zeros and terms of a polynomial. A total of 5 exercises are present in this chapter, which includes problems related to all the topics mentioned in the chapter.

Topics Covered in Class 9 Maths Chapter 2 Polynomials

Definition of a polynomial in one variable, its coefficients, with examples and counter examples, its terms, zero polynomial. Degree of a polynomial. Constant, linear, quadratic, cubic polynomials; monomials, binomials, trinomials. Factors and multiples. Zeros/roots of a polynomial/equation. State and motivate the Remainder Theorem with examples and analogy to integers. Statement and proof of the Factor Theorem. Factorisation of ax 2 + bx + c, a ≠ 0 where a, b, c are real numbers, and of cubic polynomials using the Factor Theorem.

Recall algebraic expressions and identities. Further identities of the type:

(x + y + z) 2 = x 2 + y 2 + z 2  + 2xy + 2yz + 2zx

(x ± y) 3  = x 3  ± y 3 ± 3xy (x ± y)

x 3  + y 3 + z 3 – 3xyz = (x + y + z) (x 2 + y 2 + z 2 – xy – yz – zx)

and their use in the factorisation of polynomials. Simple expressions are reducible to these polynomials.

Important Formulas –

(x + y) 2 = x 2 + 2xy + y 2

(x – y) 2 = x 2 – 2xy + y 2

x 2 – y 2 = (x + y) (x – y)

(x + y + z) 2 = x 2 + y 2 + z 2 + 2xy + 2yz + 2zx

(x + y) 3 = x 3 + y 3 + 3xy(x + y)

(x – y) 3 = x 3 – y 3 – 3xy(x – y)

x 3 + y 3 + z 3 – 3xyz = (x + y + z) (x 2 + y 2 + z 2 – xy – yz – zx)

Dividend = (Divisor × Quotient) + Remainder

Remainder Theorem

Let p(x) be any polynomial of degree greater than or equal to one, and let a be any real number. If p(x) is divided by the linear polynomial x – a, then the remainder is p(a).

Factor Theorem

If p(x) is a polynomial of degree n > 1 and a is any real number, then (i) x – a is a factor of p(x), if p(a) = 0, and (ii) p(a) = 0, if x – a is a factor of p(x).

NCERT Solutions Class 9 Maths Chapter 14 Statistics

The branch of Mathematics in which the extraction of meaningful information is studied is known as Statistics. It can also be defined as the collection of data on different aspects of the life of people useful to the State. The chapter teaches about the different presentations of the data, including the frequency distribution as well. The chapter also helps the students learn the graphical representation of data using different graphs such as Bar graphs, Histograms, Frequency polygons, etc. The chapter also lets the students learn the measure of central tendency mean, median and mode of the raw data. A total of 4 exercises are present in the chapter that includes problems related to all these concepts.

Topics Covered in Class 9 Maths Chapter 14 Statistics:

Introduction to Statistics: Collection of data, presentation of data – tabular form, ungrouped/grouped, bar graphs, histograms (with varying base lengths), frequency polygons, qualitative analysis of data to choose the correct form of presentation for the collected data. Mean, median, and mode of ungrouped data.

Statistics deals with the collection, presentation, and analysis of data, as well as the drawing of meaningful conclusions from the data.

Mean – It is found by adding all the values of the observations and dividing it by the total number of observations. It is denoted by \(\begin{array}{l}\overline{x}\end{array} \) .

So, \(\begin{array}{l}\overline{x}=\frac{\sum_{i=1}^{n}x_{i}}{n}\end{array} \)

For an ungrouped frequency distribution, it is \(\begin{array}{l}\overline{x}=\frac{\sum_{i=1}^{n}f_{i}x_{i}}{\sum_{i=1}^{n}f_{i}}\end{array} \)

Median – It is the value of the middle-most observation (s).

If n is an odd number, the median = value of the [(n + 1)/2] th observation

If n is an even number, median = Mean of the values of the (n/2) th and [(n/2) + 1] th observations.

Mode – The mode is the most frequently occurring observation.

Apart from understanding the question and question paper pattern, you will even be able to manage your time properly. Time management is very important when it comes to writing an exam. You must know which section to pay more attention to and which section you will be able to finish quickly. Practicing with sample papers and other question banks will help you to manage your time accordingly.

Do not make a habit of procrastinating and allow your mind sufficient time to get a grasp of new concepts.  Start your preparation early and spare the last few days for exams. Prior to the exams, make sure you have covered all the topics beforehand. Learning new things just before the exams will not be favourable. Also, if you get study leaves before your exams then utilize those days carefully. Make a timetable and chalk out your subjects. Science subjects need more time to practice so allot at least 2-3 hours in a day for Science. Practice the numericals in the first hour and then spend another hour on revision and reading. You should also solve a few questions every day. Try to sit to study as early in the morning as possible when your mind is fresh. This is the time when your mind is the most active. If you have someone at home to help you out with studies, ask him/her to sit with you and check your answers when you solve them. Go through the corrections yourself to know where you went wrong. If you do not have anyone to help you out, try to do it yourself.

You should also understand that referring to NCERT Solutions for Class 9 Science is considered to be sufficient to prepare for your examinations. These solutions are framed by Vedantu keeping in mind the abilities of students. These solutions are provided in detail to help you easily understand all the complex topics and concepts. You can even learn technique and tricks to understand the topics better. In order for you to get an overall idea of the concepts, you must start to prepare for your exam beforehand.

Some Other Vital Suggestions for Studying

Another suggestion to study better is to have group studies. However, for this purpose, you and your group have to be really serious and dedicated. When you study in groups, you help each other to understand topics better. When you try to explain something to your friend, your own concepts are clarified better. This way both you and your friend benefit from a group study session. This is something you should always keep in mind since you have to ensure full utilization of these sessions. This is a good habit to have, particularly before the examinations.

Make a habit of solving question papers from the previous year. This will help you to get a hold of the different topics and question patterns usually followed in the exam. In case you do not have the previous years’ question papers, then get hold of some mock test question papers or sample test papers. Solving them is beneficial as you will be fully prepared with the format. Having a set of formulas ready for revision helps you with solving the sums. When you are revising through chapters that require you to do sums, have a separate notebook for writing down the formula. This book is of great help for last moment revision. You will not have to go through page after page looking for the formulas. All you need to do is open the notebook and check the formulas you need. This will help you stay abreast of the important formulas without having to really fret about finding them all over again in case you forget. A common scenario isn’t it? Well, a little strategy will help you overcome these hurdles with ease.

If you are a student who has problems with maths, you will need to practice a bit more than the others. Your theory should be well-prepared so that you can score better in that part. If you have the fear of mathematics, then make it a point to overcome that fear. Do not worry! Maths is not that difficult! All you have to do is forget the difficulty and practice daily. That is the only mantra behind acing maths. Just wake up in the morning and practice 2-3 sums from each chapter. Read the questions carefully before attempting the problem. Understand what it wants and what is already given. Go ahead with it when you understand the question properly.

One more important tip before exams that one must follow is being less distracted. You may think your guardian is being absolutely ruthless when he/she asks you not to watch TV before exams. But what he/she means is that you should wisely utilize your time and distract your mind. It is very important to get into that mindset of studying before exams. Try not getting disturbed or distracted as your mind needs to be in the right state to help you prepare. Allot a specific time for activities such as watching TV or playing video games. Make a time table for that too. You can study the whole day and have a recess period of 2 hours after studying, preferably at night before you go to bed.

Before you write your exam you must make sure that you do a complete revision at least 3 times. Make sure that you don’t learn any new topics one night before the exam. This will only lead to confusion and you might even forget the other topics and concepts that you learned. You should revise one day before the exam, during the night, and then you can do a quick revision in the morning. With the notes that you have, revising concepts and topics will make it easier for you to do. For Class 9 Science , it is important for you to revise how to draw all the diagrams that are required for the examination. This will help you score better marks.

What Else Should You Know While Preparing?

Eating and sleeping sufficiently before exams are very necessary for your body. Eat your food on time and sleep on time. Do not compromise on sleep or go to bed late just the night before your exam. This can cause severe headaches in the morning, potentially making you fall sick while writing your exam. Take proper food with a balanced diet plan so that both your body and mind are healthy.

Lastly, do not take too much pressure. If you are having a problem with any chapter, just get help from Vedantu. Do not stress too much and take short breaks in between study hours. Sitting for long periods can give you back pain and stress you out. Start with the difficult chapters first and then move on to the chapters you find easy. Keep your notes and books arranged so that you do not have to get up repeatedly. Keep cell phones and video games away from the study table. Anything that distracts you should remain out of your sight.

On the day of the examination, try not to discuss what you learned with your friends. This can lead to further confusion for both you and your friends. The way you may have learned a particular concept could be different as compared to the way your friends may have learned a particular topic. Apart from this you may also get confused as to if you missed any topics while studying or not. But don’t worry, you have given your best in your preparation and you will do well according to how you have studied.

These are tried and tested methods and have yielded results for lakhs of students like you all over the country. So, wishing you all the best for your preparation for the CBSE Class 9 Science examination . We advise you to be positive, confident as well as get the concepts clear for good exam performance and a high score. Also, revise the solutions to past question papers after understanding the content of the relevant chapters.
