Factor
x² + 11x + 24

• (x + 6)(x + 4)

• (x + 10)(x + 2)

• (x + 8)(x + 3)

• (x + 2)(x + 12)

Answer explanation

To factor x² + 11x + 24, we look for two numbers that multiply to 24 and add to 11. The numbers 8 and 3 fit this, so the expression factors to (x + 8)(x + 3).

(x - 12)(x - 3)

• (x - 12)(x - 3)

• (x + 3)(x + 12)

• (x + 12)(x - 3)

• (x + 3)(x - 12)

• (x + 6)(x - 5)

• (x - 6)(x - 5)

• (x + 6)(x + 5)

• (x - 6)(x + 5)

x² - 9x + 18

• (x + 6) (x + 3)

• (x - 6) (x - 3)

• (x - 2) (x - 9)

• (x + 2) (x + 9)

x² - 9x - 22

• (x + 11) (x - 2)

• (x + 2) (x - 11)

• (x - 11) (x - 2)

• (x + 2) (x + 11)
