Problem is, I assume that the u will be ln(4+x^2) and the dv will be xdx, but when I solve for that, my equation ends up being:

$\displaystyle \frac {\1}{2}x^2ln(4+x^2) - \int \frac {x^3}{4+x^2}dx$

...which may be right, but I don't know what my next step should be. Any help on this would be greatly appreciated, just having a total brainfart with this one.

Edit: only took 50 tries to get both equations formatted right... you know you're a noob when... :P
