Exploring Equivalent Algebraic Expressions

Mrs. Vandenberg guides students through the process of writing equivalent algebraic expressions by factoring using the greatest common factor (GCF) and expanding using the distributive property. The lesson includes multiple examples, starting with simple expressions and advancing to more complex ones. Students are encouraged to use division ladders to find the GCF and verify their work using the distributive property. The video concludes with instructions for homework, emphasizing the importance of showing all work clearly.
