Solving Quadratics

Convert x²-6x+9 to factored form and identify the solution.

• (x-3)(x-3); x=3
• (x+3)(x+3); x=-3
• (x+4)(x+2); x=-4, -2
• Not factorable

Solve by factoring

x² + 2x - 24 = 0

• x = -6, x = 4

• x = 6, x = -4

Solve by factoring

x² + 9x + 20 = 0

• x = -2, x = -10

• x = -3, x = -4

• x = -4, x = -5

• x = -4, x = -6

Solve by factoring

x² + 7x + 12 = 0

• x = -2, x = -10

• x = -3, x = -4

• x = -4, x = -5
