Example: 3x 2 + 9x + 6

2
Solving Quadratic Equations

3
Quadratic Equation: An equation with the highest power being x 2

4
To Solve a Quadratic Function: 1.If necessary, rewrite the equation so that it is equal to zero

5
To Solve a Quadratic Function: 1.If necessary, rewrite the equation so that it is equal to zero 2.Factor the expression

6

9
Example 1: x 2 + 5x + 4 = 0

10
Example 2: x 2 + 3x = 28

11
Example 3: x 2 = 6x – 8

12
Example 4: x 2 – 7x = 3 – 9x

13
Practice 1: x 2 + 10x + 24 = 0

14
Practice 2: x 2 + 9x = –18

15
Practice 3: x 2 + 12x = 5x – 10
