(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

[tex]\int\frac{x^3 dx}{(x+1)^8}[/tex]

2. Relevant equations

None I can think of.

3. The attempt at a solution

Hm..I just don't know where to start.

No substitution seems to be useful. (u=x+1, u=(x+1)^8).

I've tried pulling x out of the denominator to get:

[tex]\int\frac{x^3 dx}{x^8 (1+x^-1)^8}[/tex]

but that doesn't help either..

This isn't really HW just one of 15 integrals I was given that I should be able to do...

Thanks in Advance for any hints on solving this.
