1. 4.8 “The Quadratic Formula” Steps: 1.Get the equation in the correct form. 2.Identify a, b, & c. 3.Plug numbers into the formula. 4.Solve, then simplify if possible.

2. I. Equations With Two Real Solutions 2. x 2 – 5x = 7

3. II. Equations With One Real Solution Find the solutions to the following quadratic equations: 3. 25x 2 – 18x = 12x – 9 4. 16x 2 – 23x = 17x – 25

4. III. Equations With Imaginary Solutions Find the solutions to the following quadratic equations: 5. – x 2 + 4x = 5 6. 4x 2 + 3x + 12 = 3 – 3x

5. Try These 7. 7x 2 – 2x = 58. – 5x 2 + 3x + 1 = 6 – 7x
