iren [92.7K]

Answer:

See below

Step-by-step explanation:

<u>Given function</u>

f(x)=x³ + 3x²- 7x - 21

<u>We can find its factors:</u>

x³ + 3x² - 7x - 21 =
x²(x + 3) - 7(x + 3) =
(x² - 7)(x + 3)

We can conclude that the given polynomial function is fully divisible by (x + 3) and the quotient is (x² - 7)

Also one of zeros of the function is -3
