You have the correct answer. It is choice A. Nice work.
To prove that (x+3) is a factor, plug x = -3 into f(x) and you should get 0 as a result. This is using the remainder theorem.
If you were to divide f(x) over (x+3), you should get x^2+2x-2 as the quotient. Solve x^2+2x-2=0 through the quadratic formula and you should get the following:
or
or
or
or
or
or
or
which help set up the other factor of the answer
Note: if x = k is a root, then x-k is a factor
So if is a root, then is a factor
