mark i did that method where you y cancels out but then it does not staisfy both of your equation which is x^2-y^2+3x and 2xy+3y=0 :-)

one more thing is it Argz = z+3 or z(z+3) ??? im getting even more confused because no way in the world can an argument be 90 degree unless it only has an imaginary number ? ??? soo it will help if you give us the mod

yanny i dont think u can get tan 90 its undefiend ?? unless its something else becuase your arg= tan y/x ?? hmm still cant seem to figure it out can u like give us the mod :-)
