What is the formula of a3_b3?
Note – The formula for (a−b)3 can easily be derived by writing (a−b)3=(a−b)(a−b)2. Then using the algebraic identity that (a−b)2=a2+b2−2ab, we can write (a−b)3=(a−b)(a2+b2−2ab), on simplification of this right hand side will help us getting the value of(a−b)3.

What is the formula of a cube and B Cube?
We call the minus form the difference of cubes. The formula for the minus form is this: a^3 – b^3 = (a – b)(a^2 + ab + b^2). The plus form is called the sum of cubes, and the formula for this form is this: a^3 + b^3 = (a + b)(a^2 – ab + b^2).
