Is this the correct problem: %28%286x%5E2%29%2F%288x%29%29%2A%28+%28-4x%5E3%29%2F%282x%5E2%29%29?

If so, multiply numerator times numerator and denominator times denominator:
%28-24x%5E5%29%2F%2816x%5E3%29

This fraction reduces by dividing out an 8 factor and also x%5E3. When you divide variables with the same base number, remember that you SUBTRACT exponents.
%28-24x%5E5%29%2F%2816x%5E3%29
-3x%5E2%2F2%29
