Question

If x+4 Is a Factor Of The Polynomial x³-x²-14x+24 ,Then Find Other Factors.​

Answer 1

(x - 3) and (x - 2)

Explanation:

Using the method of long division to divide the polynomial by x + 4

x² - 5x + 6

-------------------------------

x + 4 | x³ - x² - 14x + 24

x³ + 4x²

---------------------------

- 5x² - 14x + 24

- 5x² - 20x

-------------------------------

6x + 24

6x + 24

--------------------------------

0 0

The quotient is x² - 5x + 6 = (x - 2)(x - 3)

x³ - x² - 14x + 24 = (x - 2)(x - 3)(x + 4) ← in factored form
