WebThe sum or difference of two cubes can be factored into a product of a binomial times a trinomial. That is, a 3 - b 3 = (a - b)(a 2 + ab + b 2). a 3 + b 3 = (a + b)(a 2 + ab + b 2). When we have an expression like a 3 - b 3 or a 3 + b 3, we can write it as product of a binomial and a trinomial. Sum of Two Cubes WebThis leads to the difference of cubes factorization, In addition, if is odd: This also leads to the formula for the sum of cubes, Another way to discover these factorizations is the following: the expression is equal to zero if . If one factorizes a product which is equal to zero, one of the factors must be equal to zero, so must have a factor of .
