\[\boxed{\mathbf{1054\ (1045)}\mathbf{.}\mathbf{\ }Еуроки\ - \ ДЗ\ без\ мороки}\]
\[1)\ (x + 1,2)(x + 5)(x - 10) = 0\]
\[x + 1,2 = 0\]
\[x = - 1,2\]
\[x + 5 = 0\]
\[x = - 5\]
\[x - 10 = 0\]
\[x = 10\]
\[Ответ:\ - 5;\ - 1,2;\ \ 10.\]
\[2)\ (x + 1)(x - 2) = 0\]
\[x + 1 = 0\]
\[x = - 1\]
\[x - 2 = 0\]
\[x = 2\]
\[Ответ:\ - 1;\ \ 2.\]
