We have a vanishing polynomial Z(X) = X^N - 1. Implicitly we are proving that

X^N = 1

What are the solutions to this polynomial? Well the answer is \omega which is any root of 1.

Therefore the solution to the formula X^N - 1 will be all the values of X^N = 1 or

X^N - 1 = (\omega - 1)(\omega^2 - 1)\cdots(\omega^{N - 1} - 1)
