Question

x* y = x -[-y] + [-5] is

Answer 1

Answer:

Separate the real terms in the equation from the imaginary parts to get two equations to get

x2−y2=5

y=2x .

Combine these two equations to get

x4−5x2−4=0 .

This equation has four solutions,

x=±(12(5±4112)12 .

The corresponding values of y can be had from the second equation.

Not to be hyperbolic about it, but What you have here are two intersecting hyperbolas.
