When you're asked to do any kind of factoring, you should always look for a greatest common factor, or GCF, first. In the trinomials presented here, we factor out a a GCF and then are left with a trinomial where the leading coefficient is one. From there, we factor by looking for two integers that multiply to the last term of the trinomial and sum to the middle term.
