This document provides instructions for factoring binomial and trinomial expressions. It explains that factoring trinomials involves first finding the greatest common factor (GCF), and if the expression has a power of x greater than two after factoring the GCF, to move to another step. It also discusses using the quadratic formula to factor trinomials if none of the factor combinations are correct. The goal is to help the reader learn how to factor binomials and trinomials.
