w is one of the complex roots of 1.
Show that w^2 + w + 1 = 0.
No fuckin' clue.

I think that equation is only true for the complex cube roots of 1 (multiply the equation by w, and you get the same equation back).

x^3 - 1 = 0.
w is only a solution if w^3=1.
Now divide through by (w-1)
x^3 - 1 / x - 1 = x^2 + x + 1
now w is only a solution if w^3 = 1 and w =! 1.
Obvious algebra is obvious
