    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}
