Homework Help: math

when I have (2x^(3)-18x)-(2x^(3)) / (x^(2)-9)
am I suppose to be left with -18x/(x^(2)-9) or is it just 18x?

Please help and thanks!

If the numerator is [ 2x^(3)-18x)-(2x^(3))] = -18x, then your first answer is correct. If only 2x^3 is in the numerator, then neither is correct
