$$x_{1} = \frac{1}{2} + \frac{\sqrt{31}}{2}$$
=
$$\frac{1}{2} + \frac{\sqrt{31}}{2}$$
=
3.28388218141501
$$y_{1} = - \frac{1}{2} + \frac{\sqrt{31}}{2}$$
=
$$- \frac{1}{2} + \frac{\sqrt{31}}{2}$$
=
2.28388218141501
$$x_{2} = - \frac{\sqrt{31}}{2} + \frac{1}{2}$$
=
$$- \frac{\sqrt{31}}{2} + \frac{1}{2}$$
=
-2.28388218141501
$$y_{2} = - \frac{\sqrt{31}}{2} - \frac{1}{2}$$
=
$$- \frac{\sqrt{31}}{2} - \frac{1}{2}$$
=
