In this lesson, you will learn that if we rearrange and rewrite the expression on one side of a quadratic equation to be a perfect square (that is, if we complete the square) we can find the solutions of the equation.
When you finish this lesson, you will be able to:
- Explain what it means to "complete the square" and describe how to do it.
- Solve quadratic equations by completing the square and finding square roots.
Here are the activities that will help you reach those goals:
