Describe the locus defined by
|z|2-2iz+2t(1+i)=0
where z=x+iy and x, y and t are real numbers
For what values of t can x and y be found so that z satisfies the given condition?
Thank you very much!

Ok well zero can also be written as 0+0i, right? This basically means that real part is equal to zero and imaginary part is equal to zero as well.
