Hi guys and gals,

I am reading schaums outline of precalculus 2nd ed. and I am having some issues solving a few of the problems.

Can someone point me to a tutorial that can help me factor equations like this:

4x^6-37x^3+9

I understand how to do the more simple ones like x^2-12x+27 but the one above is throwing me for a curve.

Thanks you very much.
