WebUse the binomial theorem, which states: ∑ n = 0 k a n b k − n k! n! ( k − n)! = ( a + b) k. Use a = b = 1, that is where the 2 k comes from. The -1 is because the theorem includes the term when n = 0, whereas in your question the summation only starts at n = 1. So you must subtract the term when n = 0, which is 1, hence − 1.
