The student will be able to solve quadratic equations by factoring and using the quadratic formula.

- To the left is the graph of a quadratic equation in graphing form. You may change the values for
*a*,*h*&*k*. - Look at the graph. Graphs show us the y-values for each x-value. When we are asked,
*"When does the quadratic equation equal zero?"*, we are asked to name the x-values where the y-values are zero. - On a coordinate plane, where do the y-values equal zero?
- In this section you will be solving quadratic equations. How many times might a quadratic equation equal zero? Can you imagine situations when the equation cannot equal zero?
