If x p occurs in the expansion of (x 2 + 1/x) 2n, then prove that its coefficient is (2n)!/(4n-p/3)!(2n+p/3)!.
I assume the question as: Prove that the coefficient of x p in the expansion of x 2 + 1 x 2 n is 2 n! 4 n-p 3! 2 n + p 3! By binomial theorem, a + b n = ? k = 0 n n C k a n-k b k Here, a = x 2 and b = 1 x. Also we have 2 n in place of n.
