The formula for the cubes’ difference is a3 – b3 = (a – b) (a2 + ab + b2). The shorter diagonals on a cube’s square faces and the longer diagonals that go through its centre are of different lengths.
This formula is used to find the difference between the cubes of two numbers without actually calculating the cubes. The formula of a 3 – b 3 is also used to factorise the binomials in the form of cubes. In this article, you will learn the cube minus b cube formula along with proof and examples.
21 wrz 2024 · The a3-b3 formula is used for the calculation of the difference between two cubes and a3−b3 formula is = (a−b)(a2 + b2 + ab). On the other hand, the a3+b3 formula is a3 + b3 = 3ab(a + b) – (a + b)3 or a3 + b3 = (a2 – ab + b2)(a + b). It is one of the most important formulas in algebra and this formula finds its application in many fields.
