INTRODUCTION

The expression x + y, 2x + y, 3x − 4y, etc. are known as binomial expressions. Such expressions are represented as the sum or difference of two terms. When such binomial expressions are given with some index, the method of their expansions is known to us to some extent. For example,

(x + b)1 = x + b

(x + b)2 = x2 + 2bx + b2

(x + b)3 = x3 + 3x2b + 3xb2 + b3

(x + b)4 = x4 + 4x3b + 6x2b2 + 4xb3 + b4

These types of expansions are known as binomial expressions. If the index of binomial expression ...
