Factoring Quadratics Using the Greatest Common Factor Method

The video tutorial explains how to factor quadratic expressions by identifying and using the greatest common factor (GCF). It begins with a basic introduction to factors, using numbers like 12, 18, and 27 as examples. The concept of the greatest common factor is introduced, followed by a detailed walkthrough of factoring the expression 18x^2 - 27x by extracting the GCF. The tutorial concludes with a verification of the factoring process and a summary of the lesson.

What is the factored form of the expression after pulling out the GCF?

How can you verify that you have factored the quadratic expression correctly?
