6. Solving Quadratic Equations by Factoring What it is…..What this means…. We are not going to graph anymore….. But we are going to “solve” a quadratic by factoring and setting each ________ equal to zero Each value of ___ will give you where the parabola crosses the _________ This is called Solving the Quadratic Visualize the kickoff in a football game… When the football is placed on the ground, and where it hits the ground again, these are called the “solutions” of the quadratic

7. Solving Quadratic Equations Using Factoring Steps: ▫ Factor the Equation ▫ Set equations equal to 0 ▫ Solve for x

8. Now let’s use our own work!!!! 1.Go back to the warm up problems. 2.Set each problem equal to zero. 3.Solve for x. These are your solutions.

9. Example Write the equation of quadratic in standard form if the solutions are x = 4, and x = -6.

10. On a little piece of paper Write the equation of a quadratic in standard form if the solutions are x = 10 and x = -4
