      Mario Math Tutor explains the Sum or Difference of Cubes and how to factor.

Remember when we learned how to factor the Difference of Squares such as:

                             (x² - 25) which factors into (x - 5)(x + 5)

because these are identical binomials with opposite signs -- the middle term cancels out.

When a polynomial contains 4 terms, and it's at least a cubic, then you need to know how to factor by grouping.

In this video Mario Math Tutor covers how to choose the best method of factoring based on the polynomial.
