x-1/x square =4 root 2

Answer 2

hey mate
here is your answer

$if \: {x}^{2} + \frac{1}{ {x}^{2} } = 10 \\ {(x - \frac{1}{x}) }^{2} = {x}^{2} - 2 \times x \times \frac{1}{x} + \frac{1}{ {x}^{2} } \\ {(x - \frac{1}{x} )}^{2} = 10 - 2 \\ {(x - \frac{1}{x}) }^{2} = 8 \\ x - \frac{1}{x} = \sqrt{8} = 2 \sqrt{2}$
hope it helps
