    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.

    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
