	$x∈R\{0} y=(x/2)+((255)/(2x))±((√(x^4 +386x^2 +65025))/(2x)) z=−(x/2)+((255)/(2x))∓((√(x^4 +386x^2 +65025))/(2x))$
	$x \in R ∖ {0}$ $y = \frac{x}{2} + \frac{255}{2 x} \pm \frac{\sqrt{x^{4} + 386 x^{2} + 65025}}{2 x}$ $z = - \frac{x}{2} + \frac{255}{2 x} \mp \frac{\sqrt{x^{4} + 386 x^{2} + 65025}}{2 x}$
