## Solution for Factoring Binomials as Sum or Difference of Cubes a^3-1

Given polynomial is a^3-1

It can be expanded using a^3-b^3 formula i.e **a ^{3}-b^{3}=(a-b)(a^{2}+ab+b^{2})**

=(a)(a^2)+(-1)(a^2)+(a)(a)+(-1)(a)+(a)(1)+(-1)(1)

=(a)((a2 + a + 1))+(-1)((a2 + a + 1))

=(a - 1) (a^2 + a + 1)

So, the factors of a^3-1 are (a - 1) (a^2 + a + 1)
