Ответ:
\[x^{2} - 6x - 1 = 0\]
\[x_{1} + x_{2} = 6\]
\[x_{1}x_{2} = - 1\]
\[4x_{1} + 4x_{2} = 4 \bullet \left( x_{1} + x_{2} \right) =\]
\[= 4 \cdot 6 = 24\]
\[4x_{1} \cdot 4x_{2} = 16x_{1}x_{2} =\]
\[= 16 \cdot ( - 1) = - 16\]

\[x^{2} - 6x - 1 = 0\]
\[x_{1} + x_{2} = 6\]
\[x_{1}x_{2} = - 1\]
\[4x_{1} + 4x_{2} = 4 \bullet \left( x_{1} + x_{2} \right) =\]
\[= 4 \cdot 6 = 24\]
\[4x_{1} \cdot 4x_{2} = 16x_{1}x_{2} =\]
\[= 16 \cdot ( - 1) = - 16\]
