Решение
Быстрый ответ
$$x_{1} = \frac{3}{2} + \frac{\sqrt{21}}{2}$$
=
$$\frac{3}{2} + \frac{\sqrt{21}}{2}$$
=
$$y_{1} = - \frac{\sqrt{21}}{2} + \frac{3}{2}$$
=
$$- \frac{\sqrt{21}}{2} + \frac{3}{2}$$
=
=
$$\frac{3}{2} + \frac{\sqrt{21}}{2}$$
=
3.79128784747792
$$y_{1} = - \frac{\sqrt{21}}{2} + \frac{3}{2}$$
=
$$- \frac{\sqrt{21}}{2} + \frac{3}{2}$$
=
-0.79128784747792
$$x_{2} = - \frac{\sqrt{21}}{2} + \frac{3}{2}$$
=
$$- \frac{\sqrt{21}}{2} + \frac{3}{2}$$
=
