## Solution for Factoring Binomials as Sum or Difference of Cubes k^3-x^3

Given polynomial is k^3-x^3

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

(a-b)(a^2+ab+b^2)

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

= a^3 + a^2b + ab^2 - a^2b - ab^2 - b^3

= a^3 - b^3

=(k^1-x^1)(k^2+k^1x^1+x^2)

So, the factors of k^3-x^3 are - (- k + x) (k^2 + k x + x^2)
