# Binomial Theorem

The binomial theorem is a formula describing how to expand powers of a binomial (*x*+*a*)^{n} using binomial coefficients.

Binomial theorem is a college-level concept that would be first encountered in a discrete mathematics course covering combinatorics. It is listed in the California State Standards for Algebra II.
