# Math Help - Solving a complex variables equation

1. complex numbers aren't my strongest side of math.

It says solve this, I have no idea what to do

$\left(\frac{x-i}{x+i}\right)^3+\left(\frac{x-i}{x+i}\right)^2+\frac{x-i}{x+i}+1=0$

Solve this $z^3 +z^2 + z +1 =0$
It appears that $x=-1,0,1$ works.

3. hahahahah

Been doing the algebra for about 7 minutes on the computer (It's part of a final assignment)

But I likes this advise better also! It's no harm done, maybe I can ask you one more question or two later instead

thanks again
