( n − k)!In elementary algebra, the binomial theorem describes the algebraic expansion of powers of a binomial According to the theorem, it is possible to expand the polynomial n into a sum involving terms of the form axbyc, where the exponents b and c are nonnegative integers with b c = n, and the coefficient a of each term is a specific positive integer depending on n and b For example, 4 = x 4 4 x 3 y 6 x 2 y 2 4 x y 3 y 4 {\displaystyle ^{4}=x^{4}4x^{3}y6x^{2}y^{2}4xy^{3}yIf a binomial expression (x y) n is to be expanded, a binomial expansion formula can be used to express this in terms of the simpler expressions of the form ax by c in which 'b' and 'c' are non negative integers The value of 'a' completely depends on the value of 'n' and 'b'
