1. Section 10.6 Solve Any Quadratic Equation by using the Quadratic Formula

2. When an equation can’t be factor you can use the quadratic formula to solve ANY Quadratic Equation

3. Solve for x Solve x 2 + 2 = –3x.

4. Solve for x Solve 3x 2 + 4x – 8 = 0. Round the solutions to the nearest hundredth.

5. Word Problem A child throws a ball upward with an initial upward velocity of 15 ft/s from a height of 2 ft. If no one catches the ball, how long will it be in the air? Round to the nearest hundredth of a second. Use the vertical motion formula. h = –16t 2 + vt + c

6. Choosing an Appropriate Method We have used many different ways to solve a quadratic. Let’s list them: 1. Graphing 2. Square Root 3. Factoring 4. Quadratic Formula

7. Which method(s) would you choose to solve each equation? Justify your reasoning. 1.5x 2 + 8x – 14 = 0 2.25x 2 – 169 = 0 3. x 2 – 2x – 3 = 0 4.x 2 – 5x + 3 = 0 5. 16x 2 – 96x + 135 = 0
