9.7.0 • Lesson Overview

In this lesson, you will learn how to make decisions about the quadratic formula. We will pay close attention to each step in the solving process and analyze errors commonly made when applying the formula. You will need to consider how to verify that the solutions you obtained with the quadratic formula are correct.

When you finish this lesson, you will be able to:

  • Identify common errors when using the quadratic formula.
  • Describe some ways to tell if a number is a solution to a quadratic equation.

Here are the activities that will help you reach those goals:

  • 9.7.1: Evaluating Variable Expressions
  • 9.7.2: Common Calculation Errors When Using the Quadratic Formula
    • 9.7.2: Self Check
    • 9.7.2: Additional Resources
  • 9.7.3: Different Methods of Checking Solutions of Quadratic Equations
    • 9.7.3: Self Check
    • 9.7.3: Additional Resources
  • 9.7.4: Practice Spotting Calculation Errors

After that, you'll practice and review.

  • 9.7.5: Practice
  • 9.7.6: Lesson Summary
