Question

x minus 1 by x and x square minus one by x square if x plus one upon x is equal to under root 5​

Answer 1

what's the question??????

Answer 2

Answer:

step by step solution

As we have to remove under root first

Squaring both the

$(x + \frac{1}{x} ) {}^{2} = (\sqrt{5}) ^{2}$

$x ^{2} + \frac{1}{x ^{2} } + 2 \times x \times \frac{1}{x } =5$

${x }^{2} + \frac{1}{x {}^{2} } + 2 = 5$

${ {x}^{2} + \frac{1}{ {x}^{2} } } = 5 - 2$

${x}^{2} + \frac{1}{ {x}^{2} } = 3$

NOW WE CAN FIND THE VALUE OF X-1/X=???
