1. 5.8 The Quadratic Formula Life is not measured by the number of breaths we take, but by the moments that take our breath away.

2. Review – Warm Up Solve by Factoring:Solve by Completing the Square:

3. The Quadratic Formula (Useful when factoring by hand is not an option.)

4. Discriminant The discriminant of a quadratic equation is Quadratic Equations can have real or complex (imaginary) solutions. You can determine the type and number of solutions by finding the discriminant.

5. Determine the type and number of solutions of by using the discriminant.

6. Application Ex7) A player throws a ball up and toward a wall that is 17 ft high. The height h in feet of the ball t seconds after it leaves the player’s hand is modeled by h = –16t 2 + 25t + 6. If the ball makes it to where the wall is, will it go over the wall or hit the wall?
