Question

if x square + 1/x square is 10 , find x -1/x​

Answer 1

Answer:

8/9

Step-by-step explanation:

if ,

${x}^{2} + \frac{1}{x} = 10 \\ \frac{ {x}^{2} + 1 }{x} = 10 \\ \frac{ {x}^{2} }{x} = 10 - 1 (9) \\ ( {x}^{2} cut \: x \: and \: x \: cut1) \\ x = 9$

Then,

$= \frac{x - 1}{x} (write \: the \: value \: of \: x) \\ = \frac{9 - 1}{9} \\ = \frac{8}{9}$
