# Sum and Difference of Cubes Formula

The difference of the cubes is equal to the product of the difference of the cube roots of given two cubes and set of the sum of the squares of cube roots and product of the cube roots of given numbers. The sum of the cubes is equal to the product of the sum of the cube roots of given two cubes and set of the difference of the squares of cube roots and product of the cube roots of given numbers. The sum and difference of cubes formula are useful in the factorization of numbers.

#### Sum of Cubes Formula:

a3 + b3 = ( a + b ) (a2 - ab + b2)

#### Difference of Cubes Formula:

a3 - b3 = ( a - b ) (a2 + ab + b2)

Where,

a, b are values
