Answer:
x+2 is a factor of

Explanation:
To check: If (x+2) is a a factor of the polynomial

We need to check if x = -2 is the FACTOR of the given polynomial.
⇒ To show: f (-2) = 0
Now

Since, f(-2) = 0
⇒ -2 is the ROOT of the Polynomial f(x).
⇒(x +2) is the factor of the given polynomial.
Hence, x+2 is a factor of
