\[\left\{ \begin{matrix} y = 2x^{2} - 8x + 10 \\ y = 1 + 4x - 2x^{2}\text{\ \ \ } \\ \end{matrix} \right.\ \]
\[2x^{2} - 8x + 10 = 1 + 4x - 2x^{2}\]
\[4x^{2} - 12x + 9 = 0\]
\[(2x - 3)^{2} = 0\]
\[x = 1,\ 5\]
\[\left\{ \begin{matrix} x = 1,5\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \\ y = 1 + 6 - 4,5 \\ \end{matrix}\text{\ \ \ \ \ \ \ } \right.\ \text{\ \ \ \ }\]
\[\left\{ \begin{matrix} x = 1,5 \\ y = 2,5 \\ \end{matrix} \right.\ \]
\[Ответ:(1,\ 5;2,\ 5).\]
