# Binomial Expansion

A binomial can be viewed as an algebraic expression denoting the sum of two unlike terms. Examples of binomials are x + y, 3a -2b, x^{2} + y^{2} and so on. When the powers of binomials are expanded, the resulting polynomials display certain pattern. Binomial theorem summarizes the pattern in binomial expansions.

Binomial expansions and coefficients finds application in many other mathematical studies like binomial probabilities. Even though the general binomial expansion is intimidating in the first look, once the pattern is recognized, it is a very interesting mathematical concept to work with.
