Factoring Expressions: Key Concepts and Techniques

This video tutorial covers the process of factoring expressions by finding the greatest common factor (GCF). It begins with an introduction to the concept and then demonstrates the steps to find the GCF using examples such as 18 and 24. The tutorial further explains how to factor expressions by placing the GCF outside the parentheses and dividing each term by the GCF. The video concludes with an example of factoring the expression 72 + 18J, reinforcing the method taught.
