 {x}^{2}  -  \frac{1}{3}  =  \frac{1}{6}  {x}^{2}  \\  \\ 6 {x}^{2}  - 2 = x {}^{2}  \\ 6 {x}^{2}  -  {x}^{2}  = 2 \\ 5 {x}^{2}  = 2 \\  {x}^{2}  =  \frac{2}{5}  \\ x =   + - \frac{ \sqrt{10} }{5}    \ \\ x1 =  +  \frac{ \sqrt{10} }{5}  \\ x2 =  -  \frac{ \sqrt{10} }{5}

 \frac{ {x}^{2} }{4}  +  \frac{1}{10}  =  \frac{ {x}^{2} }{5}  +  \frac{x}{2} \\ x1 = 5 -  \sqrt{23}  \\ x2 = 5 +  \sqrt{23}

x + 6 =  \frac{4x}{x - 2}  \\ x1 =  - 2 \sqrt{3}  \\ x2 = 2 \sqrt{3}

 \frac{2x}{x - 3}  =  \frac{x + 1}{x + 3}  \\  \\  \\ x1 =  - 4 -  \sqrt{13}  \\  x2 =  - 4  +  \sqrt{13}

 \frac{x}{x - 1}  +  \frac{1}{x + 1}  =  \frac{x - 3 {x}^{2} }{ {x}^{2} - 1 }  \\ x1 =  \frac{ - 1 \sqrt{17} }{8}  \\ x2  =  \frac{ - 1 +  \sqrt{17 } }{8}
