In this lesson, you will build on the idea that both graphing and rewriting quadratic equations in the form of expression = 0 are useful strategies for solving equations. You will also review the ties between the zeros of a function and the horizontal intercepts of its graph, which you began exploring in an earlier unit.
When you finish this lesson, you will be able to:
- Explain why dividing by a variable to solve a quadratic equation is not a good strategy.
- Explain why quadratic equations can have no solutions and explain why there are none.
Here are the activities that will help you reach those goals:
- 8.5.1: Reviewing Zero Product Property
- 8.5.2: Interpreting Graphs to Solve Quadratic Equations
- 8.5.2: Self Check
- 8.5.2: Additional Resources
- 8.5.3: Choosing an Effective Strategy to Solve Quadratic Equations
- 8.5.3: Self Check
- 8.5.3: Additional Resources
- 8.5.4: Analyzing Errors When Solving Quadratic Equations
After that, you’ll practice and review.
- 8.5.5: Practice
- 8.5.6: Lesson Summary
