I am having a problem integrating in a WKBJ semi-classic integral. Well it's this : I have to integrate

[itex]\int_{0}^{\sqrt{m}E}\sqrt{E-\frac{x}{\sqrt{m}}}dx[/itex]

2. Relevant equations

Actually I don't have that much experience at integrating, so could you somehow show me how to integrate when you have a square root? Step by step this particular one, for example.

3. The attempt at a solution

I have tried setting the square root equal to a variable, t, and saying that the integral goes like

[itex]\int_{0}^{\sqrt{m}E}t^2dt[/itex] but it didn't seem to work out later on, plus I am almost sure this isn't correct.
