Okay, I've been having my head in a book, but cannot lick factoring. I'm doing fine on most other areas, but this remedial, basic concept is giving me trouble. If I have a problem like 3x(squared) - 12x + 12, I can't figure out how to factor it. Can anyone help me out? Thanks.
In this case, first look for something general to get rid of:
3x^2 - 12x + 12 = 3(x^2 - 4x + 4)
Then, with the portion in parentheses you have a familiar binomial.
