Hi guys,

I need to integrate the following equation with respect to x.

$\displaystyle

-ax + \frac{ab}{c-x}

$

where a,b and c are integers. I was advised to re-write the equation as

$\displaystyle

-ax -ab\frac{-1}{c-x}

$

and i'm pretty confident in integrating the first part of the equation, but i dont know how to integrate the last part. I'm guessing that the answer will involve ln(?) but i dont know how to work out what its meant to be the log of, so if anybody could help me i will be truely thankful as i've been trying to work this out for a while, getting nowhere!
