Binomial expansion induction proof
Inductionyields another proof of the binomial theorem. When n= 0, both sides equal 1, since x0= 1and (00)=1.{\displaystyle {\tbinom {0}{0}}=1.} Now suppose that the equality holds for a given n; we will prove it for n+ 1. For j, k≥ 0, let [f(x, y)]j,kdenote the coefficient of xjykin the polynomial f(x, y).
