In this lesson, you will use familiar tools like tables and graphs to represent quadratic functions. These tools will help you discover that finding the sum of the partial areas in a rectangle is the same as applying the distributive property to multiply out the terms in each factor.
When you finish this lesson, you will be able to:
- Rewrite quadratic expressions in different forms by using an area diagram or the distributive property.
Here are the activities that will help you reach those goals:
- 7.8.1: Area Diagrams
- 7.8.2: Using the Distributive Property to Write Equivalent Expressions
- 7.8.2: Self Check
- 7.8.2: Additional Resources
- 7.8.3: Using Diagrams to Find Equivalent Quadratic Expressions
- 7.8.3: Self Check
- 7.8.2: Additional Resources
- 7.8.4: Writing Equivalent Expressions
After that, you’ll practice and review.
- 7.8.5: Practice
- 7.8.6: Lesson Summary
