Evaluating Expressions and GCF

The video tutorial covers module 4, lesson 11 on factoring expressions. It begins with an introduction to the topic, followed by examples using numbers and variables to demonstrate factoring. The lesson emphasizes the use of models, the distributive property, and the greatest common factor (GCF) to factor expressions. Students are guided through practice problems to reinforce their understanding and are encouraged to evaluate expressions using given values for variables.
