Hi all,

I have a homework problem (not graded, so I'm not coming here to boost my grade if that was anybody's concern :P) that I got caught up on. I'm not sure what to set u equal to, I originally though square root of x but that was getting extremely messy. I was hoping you guys could help walk me through this one to give me an idea of where I should go with it.

Here's the problem:

Thanks guys!
