Expanding and Factoring Expressions: Part 1 Challenge

This video tutorial covers expanding and factoring expressions, focusing on positive numbers. It begins with an introduction to the concepts, followed by a practical example using a milkshake recipe to illustrate the distributive property. The video then introduces the rectangle method for expanding expressions, providing detailed examples and practice. The latter part of the video shifts to factoring, explaining the use of the greatest common factor (GCF) and offering examples to reinforce understanding.

What is the purpose of using the distributive property in expanding expressions?

• To change the variables

• To make an expression smaller

• To eliminate constants

• To make an expression bigger
