Heya !!!
-X -2 = 0
-X = 2
X = -2
P(X) = 2X³ - X² - 2X -8
P(-2) = 2 × (-2)³ - (-2)² - 2 × -2 - 8
=> 2 × -8 - 4 + 4 - 8
=> -16 -8
=> -24
Remainder is not equal to 0.
So,
-X -2 is not a factor of the given polynomial.

Divide the given polynomial by -(2+x) if the remainder is zero,its a factor else it isn't.However if you face any difficulty you can contact me later

In maths, a person needs to work his way out,no one should spoon feed you or else you would be suffering
