Factoring Polynomials Using the GCF

This video tutorial introduces the concept of factoring polynomials, focusing on the greatest common factor (GCF). It explains how to identify the GCF in a polynomial by examining coefficients and variables, and provides step-by-step examples to demonstrate the process. The tutorial covers several example problems, illustrating how to factor polynomials using the GCF method and verifying the results through distribution.
