I am trying to integrate $x^3(x^2+1)^5$ and I believe the starting point is to utilize long division to break up the polynomial, however I am unsure how to divide this out. Could someone give me what exactly I'm suppose to be dividing?
Edit: Well the reason I ask is if you attempt to use wolframalpha.com, they state to use long division to simplify the problem and I don't see how that's possible. My first thought was it was a parts problem.
