![\sf x^3-1^3](https://tex.z-dn.net/?f=%5Csf%20x%5E3-1%5E3)
Now, we can apply the "Difference of Cubes Formula".
![\boxed{\sf x^3-y^3=\left(x-y\right)\left(x^2+xy+y^2\right)}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Csf%20x%5E3-y%5E3%3D%5Cleft%28x-y%5Cright%29%5Cleft%28x%5E2%2Bxy%2By%5E2%5Cright%29%7D)
