\[- \frac{7}{12}\ и\ \frac{3}{2}\]
\[x_{1} + x_{2} = - \frac{7}{12} + \frac{3}{2} =\]
\[= - \frac{7}{12} + \frac{18}{12} = \frac{11}{12};\]
\[x_{1} \cdot x_{2} = - \frac{7}{12} \cdot \frac{3}{2} = - \frac{7}{8}.\]
\[Уравнение:\]
\[x^{2} - \frac{11}{12}x - \frac{7}{8} = 0\]
\[\Longrightarrow 24x^{2} - 22x - 21 = 0.\]
