1 Solving Quadratic Equations by Factoring
Section 6-2 Solving Quadratic Equations by Factoring Objective: To solve quadratic equations by factoring.

2 Vocabulary Factoring Zero Product Property GCF PST DoS Grouping
Quadratic Zero Product Property

3 Root or solution The value of the variable in an equation
Root or solution The value of the variable in an equation. (also called the x-intercepts and zeros.) Double Root or Double Zero If a root or solution appears twice because it is a repeated factor, then it is a double root or double zero.

4 Zero Product Property - used to solve an equation
Zero Product Property - used to solve an equation.   1) Write the equation with zero on one side. 2) Factor the non-zero side of the equation. 3) Set each factor equal to zero and solve.

5 Example 1 Solve: x(x + 4) = 0

6 Example 2 Solve: x2 + 7x = 0

7 Example 3 Solve: x2 = x + 30

8 Example 4 Solve: 35x3 + 16x2 = 12x
