Hey guys/gals,

I have a problem involving integration by parts that has me stumped. Here is the equation:

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:

...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
