SOLUTION:
We are to find the expression that is a factor of the given polynomial.
We try all the given options by substituting the value of x after equating it to zero and any of the options that gives zero is a factor.
Trying option ( x + 2);
We now substitute, x = -2 into the given polynomial.
Since the result gives zero, so ( x + 2 ) is a factor of the given polynomial.
