Factoring Out the Greatest Common Factor (GCF)

The video tutorial explains the process of factoring out the greatest common factor (GCF) from expressions. It begins by distinguishing between equations and expressions, emphasizing the importance of identifying common factors. The tutorial demonstrates how to factor out the GCF, using the example of dividing terms by three to simplify an expression. The process is explained as rewriting an expression as a product, ensuring the original expression can be reconstructed by multiplying the factors. The tutorial concludes with a recap of the factoring process and its significance in simplifying expressions.
