I found this had to be true in order to verify an other equality i know to be true, but the transformation is so tedious and the formula is so balanced i imagine there is a way better way to demonstrate it.

So have you tried writing it in terms of sines and cosines?

I am currently trying, there is probably some obscure trig identity like >>11480464 said

The products simplify.
What are the roots of x^n - 1? Just e^(2*pi*i*k/n).
The products simplify to
(e^(i*n*t) - 1)(e^(-i*n*t) - 1) = -(e^(i*n*t) - 1) - (e^(-i*n*t) - 1)
which is obviously true for all t in C.

I'm sure any of those identities are covered by the identities of cyclotomic polynomials.
And then you're dealing with x and its conjugate.

some retard wrote the symbol for subtraction instead of a factor of (-1)
