As a trap, I would've thought some people correctly read that as PQ is represented by a+ib and then just obtain the result by multiplication of i as their answer without considering the complex number represented by P.

On Wolfram, the graph looks like it intercepts the y-axis and x-axis. I did what you did, but wolfram graphed something weird.
