'z^2 − z' 'z' SOLVE

I just get:
{z=0 z=1}

It's the correct answer (for example 'z²=-1' 'z' SOLVE returns {z=-i , z=i }

Uncheck flag 128 (Cmplx var allowed)
Complex mode

Then do

'z^2-z=0' ABS

and you get the result with RE and IM parts....

Code:

'SQRT(RE(z)^4+(2*IM(z)^2+2)*RE(z)^2+(IM(z)^4-2*IM(z)^2+1))=0'
