$$x_{1} = - \frac{1}{2} + \frac{\sqrt{21}}{2}$$
=
$$- \frac{1}{2} + \frac{\sqrt{21}}{2}$$
=
1.79128784747792
$$y_{1} = - \frac{\sqrt{21}}{2} + \frac{3}{2}$$
=
$$- \frac{\sqrt{21}}{2} + \frac{3}{2}$$
=
-0.79128784747792
$$x_{2} = - \frac{\sqrt{21}}{2} - \frac{1}{2}$$
=
$$- \frac{\sqrt{21}}{2} - \frac{1}{2}$$
=
-2.79128784747792
$$y_{2} = \frac{3}{2} + \frac{\sqrt{21}}{2}$$
=
$$\frac{3}{2} + \frac{\sqrt{21}}{2}$$
=
