Question

if x2+1/x2=102 then x-1/x​

Answer 1

Step-by-step explanation:

⚪ANSWER⚪

we know that,

we know that,

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

==⤵

${x - \frac{ {1}^{2} }{?x} } = 102 - 2 = 100$

==⤵

$x - \frac{1}{?x} = \sqrt{100 } = 10$

===⤵

Therefore:-

$x - \frac{1}{?x} = 10$
