# Math Help - another root integral

1. ## another root integral

Hi. I'm doing some review questions, and I'm not sure what to do with this integral:

$\int{x\sqrt{x-2}\,dx}$

I suppose I could try integration by parts. But the review question is from a section before we learned that, so presumably there must be a another approach.

Change it to $\int{(u+2)\sqrt{u}\,du}$
