Solving Quadratic Equations

Use factoring to find the solutions of the quadratic equation :

x² + 2x - 15 = 0

• x = 3 or x = 5

• x = 5 or x = -3

• x = -5 or x = 3

• x = -3 or x = -5

Use factoring to find the solutions of the quadratic equation:

x² + 12x + 35 = 0

• x = -5 or x = -7

• x = 5 or x = 7

• x = -35 or x = -1

• x = -9 or x = -4

Factor x² + 6x + 9 = 0 and solve for x.

• x = -3

• x= -4, -5

• x= 3

• Not factorable

What are the solutions to this equation? (x-3)(x+2)=0

• x= 3, -2

• x= -3, 2

• x= 2, 3

• x= 3, 2

Use factoring to find the solutions of the quadratic equation:

x² - 16 = 0

• Not Factorable

• ( x - 4) ( x + 4); x = 4, -4

• ( x - 8) ( x + 8); x = 8, -8

• ( x - 4) ( x - 4); x = 4

Use factoring to find the solutions of the quadratic equation:

x² - 25 = 0

• ( x + 5 ) ( x - 5 ); x = -5, 5

• ( x - 5 ) ( x - 5 ); x = 5

• ( x + 5 ) ( x + 5 ); x = -5

• Not Factorable

Use factoring to find the solutions of the quadratic equation:

6x² - 27x = 0

• (6x+1)(x+3); x = -1/6, -3

• 3x(2x-9); x = 0, 9/2

• 6x(x-9); x = 0, 9

• (3x-9)(2x+3); x = 3, -3/2

x² - 9x + 20 = 0

• x = -2, 10

• x = -5, -4

• x = 4, 5

• Not factorable

Solve the equation:

(x- 9)(x + 3) = 0

• x = 3 or x = 9

• x = 3 or x = -9

• x + -3 or x = 9

• x = -3 or x = -9

Solve the equation:

3x ( 2x - 4) = 0

• x = -1/3 or x = -2

• x = 0 or x = 2

• x = 0 or x = -2

• x = -1/3 or x = 2
