Question

if x is equal to 1 minus root 2 you then the value of x minus one upon X will be​

Answer 1

Answer:

$x = 1 - \sqrt{2} \\ \\ so \: x - \frac{1}{x} \\ \\ =( 1 - \sqrt{2} ) - \frac{1}{(1 - \sqrt{2} )} \\ \\ = \frac{(1 - \sqrt{2}) ^{2} - 1 }{1 - \sqrt{2} } \\ \\ = \frac{1 - 2 \times 1 \times \sqrt{2} + {( \sqrt{2} )}^{2} - 1}{1 - \sqrt{2} } \\ \\ = \frac{1 - 2 \sqrt{2} + 2 - 1 }{1 - \sqrt{2} } \\ \\ = \frac{2 - 2 \sqrt{2} }{1 - \sqrt{2} } \\ \\ = \frac{1(1 - \sqrt{2} )}{1 - \sqrt{2} } \\ \\ = 1$
