\[2x² - 3x\sqrt{6} + 6 = 0\]
\[D = \left( - 3\sqrt{6} \right)^{2} - 4 \cdot 2 \cdot 6 =\]
\[= 9 \cdot 6 - 48 = 54 - 48 = 6\]
\[x_{1} = \frac{3\sqrt{6} + \sqrt{6}}{2 \cdot 2} = \frac{4\sqrt{6}}{4} = \sqrt{6}\]
\[x_{2} = \frac{3\sqrt{6} - \sqrt{6}}{2 \cdot 2} = \frac{2\sqrt{6}}{4} = \frac{\sqrt{6}}{2}\]
\[Ответ:x = \sqrt{6};x = \frac{\sqrt{6}}{2}.\]
