NCERT Solutions for Class 11 Maths Exercise 8.2

Class 11 Maths exercise 8.2 is based on general term of Binomial Theorem. You will read the same points along with the expansion of coefficients and index. Find here whether all the observation given above does make sense.

The basic objective of this explanation is to show you how the binomial theorem works and what It means to you. In simple terms, we can say the Binomial theorem shows the algebraic expansion of the exponent of a binomial. This makes it is possible to expand a polynomial (a + b)ⁿ into the multiple terms.

There are 12 questions in NCERT exercise 8.2 of 11th Maths. You may find the binomial theorem exercise 8.2 so extremely intimidating that you might question its use. If you divide the chapter into the smaller part you may find it easier to practice and study. There are only a few topics and rules that you need to do.

Not get confused along the way. Once you straightened out, your task of completing all 12 questions in exercise 8.2 is much more manageable. The chapter is more about understanding the concept. You may want to invest some extra time for theorem like Pascal’s Triangle.

Before you know about the importance of Pascal’s triangle, you may need to understand what Pascal’s triangle is all about. In simple words, in algebra, it is an triangular arrangement of numbers that provides a coefficient in the expansion of any binomials expression like (x + y)ⁿ.

It is proposed by the French mathematicians Blaise Pascal, also by Meru Prastara of Pingla. It states that if you want to find the expansion of (2x + 3y)¹², you must first be required to make rows of Pascal’s triangle till index 12. The limitation of this method is that it is a lengthy process.

There are only 12 questions in class 11 Mathematics ex. 8.2 based on the general term of Binomial expansion. All the questions are easy to solve. Question number 9, 10, 11 and 12 need more time to practice well.

Do not intimidated by the length of the solution because it contains the calculation as well as the observations. In the second part of the chapter, you will be asked to pay attention to the last topic of the chapter which is general and middle terms.
