Answer 2

Answer:

$6x { }^{2} - 6x - 2$

$= x = (6 + - \sqrt{(6 {}^{2} } - 4 \times 6 \times - 2) ) \div 2 \times 6$

$x = (6 + \sqrt{36 + 48) } \div 12 \: and \: (6 - \sqrt{36 + 48)} \div 12$

$x = (6 + 2 \sqrt{21)} \div 12 \: and \: (6 - 2 \sqrt{21)} \div 12$

$x = (3 + \sqrt{21)} \div 6 \: and \: (3 - \sqrt{21)} \div 6$
