Известно, что a<b. Сравните: -8b и -8a

\[- 8b < - 8a\]

\[\mathbf{\ }(3x - 1)(2 + 5x) = 0\]

\[3x - 1 = 0\ \ \ \ \ \ \ \ \ \ \ \ 2 + 5x = 0\]

\[3x = 1\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 5x = - 2\ \ \]

\[x = \frac{1}{3}\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ x = - 0,4\]

\[Ответ:\ \ x = \frac{1}{3}\ и\ \ x = - 0,4.\]
