is it possible to use long division when you have something of
whatever x+ whatever / x^3 + whatever. Rather than post the exact problem I thought I would just ask beacause as I try to do the long division, I seem to keep looping and cannot get rid of the x^3.
I not quite sure what you mean, but here is a good long division program (and its free).
long divide polynomials
It will show you all of the steps of any long division problem.
