Factoring is the process of turning a polynomial that is a sum or difference of terms into a product. Some people think of it as the opposite of "FOILing." One way to factor a trinomial is through guess and check- the first term in each of your factors must multiply to the ax^2 term, and the last two terms must multiply to the c, or constant term. From there, you have some guessing (guessing factor combinations) and checking (FOIL each combination to see if you get the trinomial that you started with.)
