(1) Formula for Difference Of Cubes

5%5E3%2Aa%5E3-1%5E3
%285a%29%5E3-1%5E3
%285a-1%29%28%285a%29%5E2%2B5a%2A1%2B1%5E2%29-----according to the formula
%285a-1%29%285%5Ea%5E2%2B5a%2B1%29


(2) Sum Of Cubes Formula
%28a%5E3%2Bb%5E3%29=%28a%2Bb%29%28a%5E2-ab%2Bb%5E2%29
Use the formula.


(3) Difference Of Cubes formula also.
