Answer 2

Answer:

Binomial Expression: A binomial expression is an algebraic expression which contains two dissimilar terms. Ex: a + b, a3 + b3, etc.

Binomial Theorem: Let n ∈ N,x,y,∈ R then

nΣr=0 nCr xn – r · yr + nCr xn – r · yr + …………. +  nCn-1 x · yn – 1 + nCn · yn

i.e.(x + y)n = nΣr=0 nCr xn – r · yr where,
