$x = \frac{-By \pm \sqrt{B^2y^2 -4 ACy^2}}{2A}
=\frac{-B \pm \sqrt{B^2 -4 AC}}{2A}y $
or for $y$ in terms of $x$:
$y = \frac{-Bx \pm \sqrt{B^2x^2 -4
ACx^2}}{2C} =\frac{-B \pm \sqrt{B^2 -4 AC}}{2C}x $.
However neither approach will yield non-zero real
number solutions because $\Delta = B^2 -4AC$ <
$0$.
