Factoring cubic and further polynomials
Hi, just stopped lurking on mhf and made my first post.
Ok I can factor quadratics and the differences of squares. I'm basically using the factor pairs method (finding factor pairs that add up to the b term) for quadratics as it almost always works. I can expand cubic and further polynomial brackets but I cannot do it the other way around by factorizing.
I've hit a roadblock trying to factorize these polynomials. Could anyone please help me with them?
