Simplification of algebraic formula. (a+b)^3

Basic way: (a+b)^3=(a+b)*(a+b)*(a+b) or, (a+b)^3= (a+b)*(a(a+b)+b (a+b)) or, (a+b)^3= (a+b)*(a^2+ab+ba+b^2) or, (a+b)^3=(a+b)*(a^2+2ab+b^2) or, (a+b)^3=a(a^2+2ab+b^2)+b(a^2+2ab+b^2) or, (a+b)^3=a^3+2a^2b+ab^2+a^2b+2ab^2+b^3 or, (a+b)^3=a^3+3a^2b+3ab^2+b^3 (a+b)^3-3a^2b-3ab^2=a^3+b^3
