Polynomial expansion
Looking for Taylor expansion of (1 + a + b)^n. Thanks — Preceding unsigned comment added by 163.202.48.126 (talk) 07:47, 21 August 2015 (UTC)


 * If n is a positive integer, see our article on trinomial expansion.Gandalf61 (talk) 08:39, 21 August 2015 (UTC)
 * I expect it to also generalize to complex n like with the binomial series.--Jasper Deng (talk) 04:33, 22 August 2015 (UTC)
