Binomial expansion describes the expansion of the powers of algebraic binomail expression. The binomial coefficients form a triangular array of numbers known as Pascal's Triangle, though the triangle was known to many prior to Pascal. In 1665 Issac Newton generalized the formula to allow exponents other than nonnegative integers, hence the appearance of the formula on several stamps attributed to Newton.
