I have an equation, $\displaystyle (zi)(z+i)/5 = 5 $ and I am required to find and plot the cartesian equations of the loci of z. Please help.

the solution to this is just $z = \pm 2\sqrt{6}$ 2 real points. Are you sure you've got the problem typed in correctly?

I have simplified it slightly. The original was: $\displaystyle (zi)(zi)*/mod(34i)=5$ I have found my problem. Thank you. Last edited by PenBlock; April 14th, 2017 at 07:28 PM. Reason: Problem Solved
