Binomial expansion

Binomial expression is an algebraic expression of the sum or the difference of two terms.For more click hereBinomial expansion depends on Pascal’s Triangle.

(a+b)2 = a2 + 2ab + b2

(a+b)3 = a3 + 3a2b + 3ab2 + b3

(a+b)4 = a4 + 4a3b + 6a2b2 + 4ab3 + b4

(a+b)5 = a5+5a4b + 10a3b2 + 10a2b3 + 5ab4 + b5
