Hi guys, calculus is not my strong point and I'm having a bit of difficulty trying to integrate these problems:

integrate: x(x-2)/(x-1)^3

int: x/(9-x)^1/2

Can I use u substitution here?

and also I'm not sure how to go about these problems, where I have to find the area under the curve bounded the given numbers:

1/xlnx where b=e^2 and a=e

x-1/(x+1) where b=1 and a=0

I would really appreciate it!
