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 + 6)(x - 5)

• (x - 6)(x - 5)

• (x + 6)(x + 5)

• (x - 6)(x + 5)

Factor the Trinomial:
x² - 8x + 15

• (x + 5) ( x + 3)

• (x - 5) (x - 3)

• (x + 15) (x - 1)

• (x - 7) (x - 8)

• (x - 12)(x - 3)

• (x + 3)(x + 12)

• (x + 12)(x - 3)

• (x + 3)(x - 12)

x² - 6x - 40

• (x + 4) (x - 10)

• (x + 5) (x - 8)

• (x + 10) (x - 4)

• (x + 8) (x - 5)
