1.Solve the equation. x^ 2 + 9 x + 14 = 0

2. Write the equation x(x – 14) + 45 = 0 in quadratic form and then solve it by factoring.

3.Solve the equation by using factoring. 7 x ^3 – 343 x = 0

4.Use factoring to solve the equation. 7 x ^2 + 56 x = 0

5.Use factoring to solve the equation. 5 y ^2 – 245 = 0

6.Use factoring to solve the equation. x ^2 – 16 x + 60 = 0

7.Use factoring to solve the equation. 3 z ^2 = 48 z – 165

8.Use the square root property to solve the equation. x ^2 = 9

9.Use the square root property to solve the equation.
(x-6)^2=25

10.Use completing the square to solve the equation
x ^2 + 6 x + 8 = 0.
