    It's fairly simple, I can think of a couple of ways to do it off the top of my head but I would suggest using by-parts and differentiating x^2 out as the most obvious.

    There are 4 partial integrations that need to be done in all...They're not difficult,but anyway,if you ran into trouble,please complain.

    I have ran through it. I just expected that i don't see shorter way. I didn't wanted to have such a practise in partial intregration. There realy are 4 several integrations (some of them many times). thank You all!
