Accepted Answer

\[- x^{2} = x - 6\]

\[\left\{ \begin{matrix} y = - x^{2}\text{\ \ } \\ y = x - 6 \\ \end{matrix} \right.\ \]

\[y = - x²\]

\[x\]	\[- 2\]	\[- 1\]	\[0\]	\[1\]	\[2\]
\[y\]	\[- 4\]	\[- 1\]	\[0\]	\[- 1\]	\[- 4\]

\[y = x - 6\]

\[x\]	\[2\]	\[- 3\]
\[y\]	\[- 4\]	\[- 9\]

\[(1):\ \ (2;\ - 4);\]

\[(2):\ \ ( - 3;\ - 9).\]

\[Ответ:x_{1} = 2;\ \ x_{2} = - 3.\]
