\[y = x^{2} - 14;\ \ \ x + y = 6.\]
\[Запишем\ систему:\]
\[\left\{ \begin{matrix} y = 6 - x\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \\ x^{2} - 6 + x - 14 = 0 \\ \end{matrix} \right.\ \text{\ \ \ \ \ \ \ \ \ \ }\]
\[\left\{ \begin{matrix} y = 6 - x\ \ \ \ \ \ \ \ \ \ \ \ \\ x^{2} + x - 20 = 0 \\ \end{matrix} \right.\ \ \]
\[x^{2} + x - 20 = 0\]
\[x_{1} + x_{2} = - 1;\ \ \ x_{1} \cdot x_{2} = - 20\]
\[x_{1} = - 5;\ \ \ x_{2} = 4\]
\[\left\{ \begin{matrix} x = - 5 \\ y = 11\ \\ \end{matrix} \right.\ \text{\ \ \ \ \ \ \ \ }\left\{ \begin{matrix} x = 4 \\ y = 2 \\ \end{matrix} \right.\ \]
\[Ответ:( - 5;11);\ \ (4;2).\]
