This factoring works for any binomial that can be written as a3−b3a3−b3. The discussion below includes three separate ways of demonstrating that this formula is valid.Explanation of the Formula -- Using the Sum of Cubes On the page about the sum of cubes we showed that a3+b3=a2...
x3 + y3 = (x + y)(x2 − xy + y2) [Sum of two cubes] x3 − y3 = (x − y)(x2 + xy + y2) [Difference of 2 cubes]Where do these come from? If you multiply out the right side of each, you'll get the left side of the equation....
Also, for both sums and differences of two nth powers:1. If n is prime, the second factor is a prime polynomial and so no further factorization can be done.2. If n is composite, the second factor can be factored using factoring by grouping....
