Students learn to solve quadratic equations using the quadratic formula.

Later, as learning progresses, they set up quadratic equations using known facts.

**Differentiated Learning Objectives**

- All students should be able to use the quadratic formula to solve quadratic equations where the coefficient of a = a and are equal to zero.
- Most students should be able to solve a quadratic equation using the quadratic formula.
- Some students should be able to derive the quadratic equation by completing the square and using it to solve complex problems.
