x^(2)/(x+1)

I'm needing to figure out the integral of this, its on my practice final, and it looks really simple at first but I cant figure it out. Anyone able to shed some light on this?

$\displaystyle {x^2 \over x+1} = {(x+1)(x-1) + 1 \over x+1} = x-1 + {1\over x+1}$

Basically. You could also make the substitution u=x+1.
