Homework Statement
Solve the following equation:
[tex]z^4+z^3+z^2+z+1 = 0[/tex]
z is a complex number.
2. The attempt at a solution
I was trying to factorize it to 1st degree polynomial multiplied by 3rd degree polynomial:
[tex](z+a)(z^3+bz^2+cz+1/a) = 0[/tex]
I discovered that I need to solve 3rd degree polynomial just to do that.
[tex]a^3-a^2+1 = 0[/tex]
This is too much mess for a small homework exercise. I think that there is a technique that I am not aware of.
Thank You.
