$$x_{1} = \frac{9}{2} - \frac{\sqrt{97}}{2}$$
=
$$\frac{9}{2} - \frac{\sqrt{97}}{2}$$
=
$$y_{1} = - \frac{\sqrt{97}}{2} - \frac{9}{2}$$
=
$$- \frac{\sqrt{97}}{2} - \frac{9}{2}$$
=
=
$$\frac{9}{2} - \frac{\sqrt{97}}{2}$$
=
-0.424428900898052
$$y_{1} = - \frac{\sqrt{97}}{2} - \frac{9}{2}$$
=
$$- \frac{\sqrt{97}}{2} - \frac{9}{2}$$
=
-9.42442890089805
$$x_{2} = \frac{9}{2} + \frac{\sqrt{97}}{2}$$
=
$$\frac{9}{2} + \frac{\sqrt{97}}{2}$$
=
$$y_{2} = - \frac{9}{2} + \frac{\sqrt{97}}{2}$$
=
$$- \frac{9}{2} + \frac{\sqrt{97}}{2}$$
