Accepted Answer

\[x^{2} = - 2x + 3\]

\[\left\{ \begin{matrix} y = x²\ \ \ \ \ \ \ \ \ \ \ \\ y = - 2x + 3 \\ \end{matrix} \right.\ \]

\[y = x²\]

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

\[y = - 2x + 3\]

\[x\]	\[1\]	\[0\]	\[- 3\]
\[y\]	\[1\]	\[3\]	\[9\]

\[(1):\ \ \ ( - 3;9);\]

\[(2):\ \ (1;1).\]

\[Ответ:x_{1} = - 3;\ \ x_{2} = 1.\]
