Exploring Factor Expressions in Depth

The video tutorial explains the concept of factoring expressions using the distributive property. It uses an ice cream cone analogy to illustrate how the distributive property works by multiplying a number outside the parentheses with terms inside. The tutorial then introduces factoring as the reverse process, where common factors are identified and extracted. Several examples are provided, demonstrating the ladder method to find the greatest common factor (GCF) and factor expressions effectively.

What property is used when multiplying a number outside the parentheses by terms inside the parentheses?

• Identity Property

• Commutative Property

• Distributive Property

• Associative Property
