Solving Quadratics with Factoring

Solve x² + 12x + 20 = 0

• x = -2 x = -10

• x = 2. x = 10

• x = 12 x = 20

• x = -3 x = -1

What are the solutions?

• x = 3

• x = 1 x= 5

• x = 1

• x = 2 x = 4

x²+4x-32=0

• x= -8, 4

• x= 8, -4

• x= -8, -4

Solve for x: (3x - 2)(x + 5)

• x = 2/3 x = 5

• x = 3 x = 5

• x = 2 x = -5

• x = 2/3 x = -5
