Introduce your class to the greatest factor on earth. The group of videos introduces factoring polynomials by finding the greatest common factor (GCF). They connect finding the GCF of the terms in a polynomial to finding the GCF of two numbers, and provide a peek into other types of polynomial factoring methods to prep class members for future concepts.
