Inegration with square roots - calc 1

[Aimee79]

1. Homework Statement [/b]
∫x/√(x-1)dx

2. Homework Equations [/b]
I'm just stumped. I have tried u substituion with
u=√(x-1)
x=u^2+1

((u^2+1)/u)du
=(u+1/u)du

but it doesn't seem to work and I can't integrate 1/u.

I just don't know where to go with this any help would be greatly appreciated.

If I were doing this question, I wouldn't make the substitution you made, but would instead use the substitution u=x-1.
