Factor Form Quadratic

Solve by factoring: x² - 9x + 20 = 0

• x = -4 and x = -5

• x = 20 and x = -9

• x = 4 and x = 5

• x = -4 and x = 5

Factor:   3x²- 6x - 24

• (3x - 8)(x + 3)

• (3x + 4)(x - 6)

• 3(x - 2)(x + 4)

• 3(x + 2)(x - 4)

Factor: 49x² - 100

• (49x + 100)(x - 1)

• (7x - 10)(7x + 10)

• (49x - 10)(x + 10)

• (7x -10)(7x - 10)
