\[\frac{3x^{2} + 11x - 4}{3x - 1}\]
\[ОДЗ:\ \ \ 3x - 1 \neq 0\]
\[\ \Longrightarrow x \neq \frac{1}{3}\]
\[3x^{2} + 11x - 4 - 3 \cdot (3x - 1) =\]
\[= 0\]
\[3x^{2} + 11x - 4 - 9x + 3 = 0\]
\[3x^{2} + 2x - 1 = 0\]
\[D = b^{2} - 4ac =\]
\[= 4 - 4 \cdot 3 \cdot ( - 1) = 4 + 12 = 16\]
\[x_{1} = \frac{- 2 + 4}{6} = \frac{2}{6} =\]
\[= \frac{1}{3}\ (не\ подходит\ по\ ОДЗ)\]
\[x_{2} = \frac{- 2 - 4}{6} = - \frac{6}{6} = - 1\]
\[Ответ:x = - 1.\]
