## What will you learn in CBSE Class 11 Maths Chapter 8 Binomial Theorem?

In previous classes, the students have learned how to find the squares and cubes of binomials like (a + b) and (a – b). Using them, they can evaluate the numerical values of numbers such as (98)2 = (100 – 2)2 , (999)3 = (1000 – 1)3, more.

But for higher powers such as (98)5, (101)6, the calculations become difficult & this difficulty was overcome by a theorem i.e Binomial Theorem that provides an easier way to expand (a + b)n, where n is an integer or a rational number. In class 11 maths chapter 8 solutions, they will study the Binomial Theorem for positive integral indices only. In elementary algebra, the binomial theorem defines the algebraic expansion of powers of a binomial.

The students well versed in the history of Binomial Theorem, statement and proof of the binomial theorem for positive integral indices, Pascal’s triangle, General and middle term in binomial expansion, & simple applications of Binomial theorem.

The major concepts of Maths covered in class 11 maths chapter 8 are:

- Introduction to Binomial Theorem
- Binomial Theorem for Positive Integral Indices (Pascal’s Triangle)
- Binomial theorem for any positive integer n,
- Some special cases

- General and Middle Terms

### Theorems and formulas used in chapter

- The expansion of a binomial for any positive integral n is given by the Binomial Theorem i.e (a+b)n = nC0 an + nC1 an – 1b + nC2 an – 2b2 + …+ nCn – 1a.bn – 1 + nCn bn

- The coefficients of the expansions are arranged in an array which is called Pascal’s triangle.

- The general term of an expansion (a + b)n is Tr + 1 = nCr an – r . br
