Factoring Trinomials by Using the GCF
Factor trinomials efficiently by first extracting the greatest common factor, then factoring the remaining trinomial to fully simplify the expression in Grade 9 Algebra.
Key Concepts
New Concept The terms of a polynomial that is factored completely will have no common factors other than 1. What’s next Next, you will apply this principle to factor various trinomials, starting by identifying and extracting the greatest common factor (GCF).
