\[x_{1} = 3;\ \ \ \ x_{2} = \frac{2}{3}:\]
\[\left( x - x_{1} \right)\left( x - x_{2} \right) = 0\]
\[(x - 3)\left( x - \frac{2}{3} \right) = 0\]
\[x^{2} - \frac{2}{3}x - 3x + 2 = 0\ \ \ \ \ | \cdot 3\]
\[3x^{2} - 2x - 9x + 6 = 0\]
\[3x^{2} - 11x + 6 = 0.\]
\[Ответ:уравнение\ 3x^{2} - 11x + 6 = 0.\]
