FactoringIt's amazing how the higher up in math you go, simple problems such as factoring will fade away almost instantly. I need to factor this... x^3-27 ...and I haven't the slightest idea on how to get started. I know the answer is... (x-3)(x^2+3x+9) ...but I can't for the life of me figure out how to get from a to b. Ugh...is math really this frustrating? Please help! |
