Factoring a <sup>3</sup> - b <sup>3</sup>. An expression of the form a <sup>3</sup> - b <sup>3</sup> is called a difference of
cubes. The factored form of a <sup>3</sup> - b <sup>3</sup> is (a - b)(a <sup>2</sup> + ab + b <sup>2</sup>) : (a - b)(a <sup>2</sup> + ab + b
First factor out the cube root of x%5E3 and the cube root of 8. That gives you a
binomial times a trinomial. That trinomial cannot be factored anymore.
