I'm back, how do I integrate (x^2+2)^2? I need to integrate this to find the volume of a solid. Cheers
Well, with higher powers you can use the binomial theorem, but it's likely not to give you a nice form.
Otherwise, see if you can have something in the form $\displaystyle u'(x) [u(x)]^n$ which has the following antiderivative : $\displaystyle \frac{[u(x)]^{n+1}}{n+1}+C$
