Hello, Im trying to solve(adsbygoogle = window.adsbygoogle || []).push({});

(z^4-2+i)(z^2+1-i)=0

With the quadratic formula:

(z^2+1-i)=0

Does a=1, b=1 & c=-1?

Thanks for your time.

IM meant to

(a) Give answers in polar form using the principal argument;

(b) Give answers in cartesian form

Cartesian is (x,y) is it not and polar is (r,theta) Im just not sure about the principal argument.
