Factoring Expressions in Algebra

The video tutorial explains how to factor expressions by finding the greatest common factor (GCF). It provides multiple examples, demonstrating the process of identifying the GCF and using it to factor terms. The tutorial emphasizes checking the results using the distributive property and highlights the importance of understanding the GCF concept.

What is the first step in factoring expressions?

• Subtracting the terms

• Adding the terms

• Finding the greatest common factor

• Finding the least common multiple
