Staff Review
This lesson tackles some more difficult and trickier trinomials. Some ideas covered are trinomials that don't factor and trinomials that don't have a leading coefficient of 1. Also, the first step of any factoring problem, taking out the greatest common factor, is explained. The very common problem of finding all middle coefficients so that a trinomial could be factored is also solved.
