Evaluate the integral

[itex]\int \frac{(a-x)^{r/s-1}}{(b-x)^{r/2}}dx[/itex]

2. Relevant equations

given: s>r

3. The attempt at a solution

I tried using a substitution:

let u=b-x

so du=-dx

this gives:

[itex]-\int \frac{(a-b+u)^{r/s-1}}{u^{r/2}}du[/itex]

I don't know what i should do after this, and i think this substitution will take me nowhere.

Does anyone have any ideas?

Thank you in advance.
