1. The problem statement, all variables and given/known data Integrate x2(2+x3)4dx. Show that Wolfram Alpha's answer is equivalent to your answer. 2. Relevant equations No equations besides knowing that the integral of xpower is 1/power+1 * xpower + 1 3. The attempt at a solution So I have the answer to the integral by hand as (2+x3)5)/15 + C. When I go to Wolfram Alpha it gives x15/15 + 2x12/3 + 8x9/3 + 16x6/3 + 16x3/3 + C I really truly have no idea how these two are the same. I tried multiple types of manipulation to my answer, but I am completely lost on where basically every factor comes from besides the first x15/15. Any help will be appreciated!!!
