Answer:

One root of f(x) = x³ + x² - 22x - 40 is 5. If 5 is a root of the function, then  

✔ x - 5

is a factor.

The result of dividing (x3 + x2 – 22x – 40) by

(x – 5) is x2 + 6x + 8. Select all of the factor(s) of x2 + 6x + 8.

✔ (x + 4)

✔ (x + 2)

The completely factored form of the polynomial is f(x) =  

✔ (x – 5)(x + 2)(x + 4)
