Ответ:

$x {}^{2} - 4 x + \sqrt{3 } = 0 \\ d = {4}^{2} - 4 \times \sqrt{3} = 16 - 4 \sqrt{3 } = 4(4 - \sqrt{3} ) = \sqrt{4(4 - \sqrt{3} } ) = 2 \sqrt{4 - \sqrt{3 } } \\ x = \frac{4 + 2 \sqrt{4 - \sqrt{3} } }{2} = 2 + \sqrt{4 - \sqrt{3} } \\ x = \frac{4 - 2 \sqrt{4 - \sqrt{3} } }{2} = 2 - \sqrt{4 - \sqrt{3} }$
