\[\boxed{\mathbf{324}.}\]
\[1)\ P(x) = x^{4} - 2x^{3} - 13x^{2} +\]
\[+ 14x + 24;\ \ a = - 1.\]
\[P( - 1) = 1 + 2 - 13 -\]
\[- 14 + 24 = 0.\]
\[P( - 3) = 0;\ \ P(2) = 0;\ \]
\[\text{\ P}(4) = 0.\]
\[Ответ:\ - 3;\ - 1;\ \ 2;\ \ 4.\]
\[2)\ P(x) = 6x^{4} + 5x^{3} - 14x^{2} +\]
\[+ x + 2;\ \ a = 0:\]
\[P(1) = 6 + 5 - 14 + 1 + 2 = 0.\]
\[D(2) = \left\{ \pm 2;\ \pm 1 \right\}.\]
\[P( - 2) = 0.\]
\[Ответ:\ - 2;0.\]
