Ответ:
\[3x^{2} - 7x - 6 = 0\]
\[D = 49 + 72 = 121\]
\[x_{1} = \frac{7 + 11}{6} = 3;\ \]
\[x_{2} = \frac{7 - 11}{6} = - \frac{4}{6} = - \frac{2}{3}.\]
\[Ответ:\ \ x = - \frac{2}{3};\ \ x = 3.\]
\[3x^{2} - 7x - 6 = 0\]
\[D = 49 + 72 = 121\]
\[x_{1} = \frac{7 + 11}{6} = 3;\ \]
\[x_{2} = \frac{7 - 11}{6} = - \frac{4}{6} = - \frac{2}{3}.\]
\[Ответ:\ \ x = - \frac{2}{3};\ \ x = 3.\]
