In this lesson, you learned how to:

• Explain the meaning of a solution to an equation in terms of a situation.
• Write a quadratic equation that represents a situation.

Here are the activities that helped you reach those goals:

• 8.1.1: Understanding a Situation with Quadratic Equations
  • In this activity, you analyzed a graph representing a situation represented by a quadratic equation. You then used the graph to describe the situation.
• 8.1.2: Modeling a Quadratic Problem
  • In this activity, you attempted to solve a problem that was represented by a quadratic equation using any method possible, including guess and check.
  • 8.1.2: Self Check
  • 8.1.2: Additional Resources
• 8.1.3: Formulating a Quadratic Equation to Represent the Model
  • In this activity, you learned how to write a quadratic equation to represent the given situation. You also learned how to interpret the solution to this equation.
