Factoring and Prime Factorization Concepts

This video tutorial introduces the concept of factoring expressions by identifying and factoring out the greatest common factor (GCF). It emphasizes the importance of finding the GCF as the first step in any factoring problem. The tutorial provides two examples: factoring 5X + 25 and 16X - 24. For each example, the process of identifying the GCF through prime factorization is demonstrated, followed by factoring the expression and verifying the result through distribution.

What is the first step in any factoring problem?

• Find the least common multiple

• Simplify the expression

• Multiply the terms

• Factor out the greatest common factor
