Factoring is difficult but at the same time simple if you know what you're doing. Here is an equation the first thing you have to do is divide by x but only when all numbers have an x. Secondly you have to factor the rest of the equation.
x3 + 3x2 - 54x = x(x + 9)(x - 6)
All you are really doing is the reverse of the foil method and if you're not sure if your right refoil the answer. The difference between factoring and solving is factoring doesn't tell you what x='s but solving does.
