Areteem: IIB Algebra 1.22

Online Course Discussion Forum

The question is: Factor x3−8y3−z3−6xyz.

I tried expanding out (x-2y-z)^3 but it didn't seem to help...what else could I try?

Try using one of the formulas given at the beginning of the chapter. Only a few of them involve cubes, so there are not many choices to try out.

Yeah, I figured it out. I kind of had a brain fart :P Thank you so much!!
