Difference of Cubes Formula
A cube is a number multiplied by itself twice. The difference of cube formula is the formula that is used to find difference of two cubes without actually finding the cube. Suppose we have two numbers a and b then their cubes are a3and b3. Now the difference of their cubes would be, a3 – b3
In mathematics, the formula for the expression a3 – b3 is,
a3 – b3 = (a – b) (a2 + ab + b2)
It is an algebraic identity that is used to find the difference between two cubes without actually calculating the cubes. To factorize the binomials of cubes, the difference of cubes formula is used.
Difference of Cubes
Difference of Cubes is the formula in mathematics that is used to simplify the difference between two cubes. This formula is used to solve the difference of cubes without actually finding the cubes. This formula factorizes the difference of a cube and changes it into other forms. The difference of cube is also called the a3 b3 formula or the a3 – b3 formula.
In this article, we have covered the difference of cubes, the difference of cube formulas, various examples related to that formula, and others in detail.
