This lesson covers skills from the following lessons of the NCERT Math Textbook: (i) 6.1- Introduction, and (ii) 6.2 - Binomial theorem for positive integral indices
However, for higher powers like (98)5, (101)6, etc., the calculations become difficult by using repeated multiplication. This difficulty was overcome by a theorem known as binomial theorem. It gives an easier way to expand (a + b)n, where n is an integer or a rational number.
This article explains the binomial theorem formula class 11 along with some useful tips that will help students memorize it at their fingertips. List of Binomial Theorem Formula Class 11 Binomial formula helps to expand the binomial expressions such as x + a, (x - (1/x))4, and so on.

binomial expression. For example, x + a, 2 x – 3y, 3 1 1 4, 7 5 x x x y − − , etc., are all binomial expressions. 8.1.2 Binomial theorem If a and b are real numbers and n is a positive integer, then (a + b) n =C 0 na n+ nC 1 an – 1 b1 + C 2 a – 2 b2 + ..... + nC r an – r br +... + nC n bn, where nC r = n r n r− for 0 ≤ r ≤ n
The NCERT Solutions Class 11 Maths Chapter 8 covers two major topics namely - expansion of expressions using binomial theorem and pinpointing a term within an exponential expression. Both topics are very important and come with vital formulas.
