Factoring out the GCF of an expression

The video tutorial explains how to factor expressions by first considering the difference of two squares method. When this method is not applicable, the tutorial demonstrates finding the greatest common factor (GCF) of the terms. The process involves dividing each term by the GCF to simplify the expression into its factored form. The tutorial emphasizes understanding the concept of rewriting an expression as a product.

Explain the process of factoring the expression mentioned in the text.

Why is the expression considered factored after the process described?
