WebThe (a-b)^3 formula is used to calculate the cube of a binomial. The formula is also known as the cube of the difference between two terms. To find the formula of (a - b) 3, we will just multiply (a - b) (a - b) (a - b). (a - b) 3 = (a - b) (a - b) (a - b) = (a 2 - 2ab + b 2 ) (a - b) = a 3 - a 2 b - 2a 2 b + 2ab 2 + ab 2 - b 3 WebThe special product of the binomials a + b and a − b is equal to the difference of squares of the terms a and b. ∴ ( a + b) ( a − b) = a 2 − b 2. The mathematical equation expresses that the product of sum and difference basis binomials, which contain the same terms is equal to the difference of them. It is used as a formula in mathematics.
