\[x^{2} = - 2x + 3\]
\[\left\{ \begin{matrix} y = x²\ \ \ \ \ \ \ \ \ \ \ \\ y = - 2x + 3 \\ \end{matrix} \right.\ \]
\[y = x²\]
| \[x\] | \[- 2\] | \[- 1\] | \[0\] | \[1\] | \[2\] |
|---|---|---|---|---|---|
| \[y\] | \[4\] | \[1\] | \[0\] | \[1\] | \[4\] |
\[y = - 2x + 3\]
| \[x\] | \[1\] | \[0\] | \[- 3\] |
|---|---|---|---|
| \[y\] | \[1\] | \[3\] | \[9\] |
\[(1):\ \ \ ( - 3;9);\]
\[(2):\ \ (1;1).\]

\[Ответ:x_{1} = - 3;\ \ x_{2} = 1.\]
