## Homework Statement

##\int \frac{x}{\left(C-x\right)^2}dx=?##

Here ##C## is a constant

## Homework Equations

## The Attempt at a Solution

##c-x=u## then ##dx=-du##

then it becomes,

##\int \frac{u-c}{\left(u\right)^2}du##

##\int \frac{u}{u^2}-\frac{c}{u^2}du##

From there I found

##ln\left(c-x\right)+\frac{c}{c-x}##

but symbolab says its,

##ln\left(c-x\right)+\frac{x}{c-x}##

I cannot see how ??
