How would I transpose this formula so I can integrate it? I'm not good with integrating fractions or square roots.

Integrate:

Q1) =

Q2)

It's the fractions and square roots that are annoying. For the square root, I know I'd have to write two brackets out and possibly expand, but don't know how I would expand with a square root - So does the 'x' in the square root become: ? Or something along those lines..

Thanks in advance.
