Treat each term in the binomial as a separate variable. The pattern for the coefficients would go like, 1, 3, 3, 1, in accordance to what you would find if you were to do the cubing with a simple model such as %28a%2Bb%29%5E3, or referring to the Binomial Theorem.

1%2A%285x%29%5E3%2B3%285x%29%5E2%28-4y%29%2B3%285x%29%28-4y%29%5E2%2B1%28-4y%29%5E3
still requiring a bit more simplifying to finish.
