Given :

  • x + 1/x = 6

To Find :

  • Value of x - 1/x

Solution :

 \tt x +  \frac{1}{x} = 6  \\   \\ \tt By \: squaring \: both \: side \\  \\  \tt \implies \bigg( {x +  \frac{1}{x} \bigg) }^{2}  =  {6}^{2}  \\  \\ \tt \implies  {x}^{2}  +  \frac{1}{ {x}^{2} }  + 2 = 36 \\  \\ \tt \implies {x}^{2}  +  \frac{1}{ {x}^{2}  }  = 34 \\  \\ \tt Subtract \: 2 \: from \: both \: side \\  \\ \tt \implies {x}^{2}  +  \frac{1}{ {x}^{2}} - 2  = 34 - 2 \\  \\ \tt \implies { \bigg(x -  \frac{1}{x} \bigg) }^{2}  = 32 \\  \\ \tt \implies x -  \frac{1}{x}  =  \sqrt{32}  \\  \\  \tt \implies x -  \frac{1}{x}  = 4\sqrt{2}

 \large\underline{ \tt \green{Value \: of \: x -  \frac{1}{x} \: is \: 4\sqrt{2}  }}
