Question

if x minus one by x is equal to 9 find the value of x square + 1 by x square​

Answer 1

Answer:

If 3 multiply one by 3 is equal to 9 find the value of 9 multiply by 9=81 and + 1= 82

Answer 2

$\red {\huge {\underline{ \frak{Your \: answEr : }}}}$

$\large\rightarrow \tt{{x} - \frac{1}{x} = 9}$

$\blacksquare \: \frak{squaring \: both \: sides}$

$\large\rightarrow \tt{ {(x - \frac{1}{x} )}^{2} = {(9)}^{2} }$

$\large\rightarrow \tt{ {x}^{2} + \frac{1}{ {x}^{2} } - 2 \times x \times \frac{1}{x} = 81}$

$\large\rightarrow \tt{ {x}^{2} + \frac{1}{ {x}^{2} } = 81 + 2 }$

$\green{\huge\rightarrow \boxed{\tt{ {x}^{2} + \frac{1}{ {x}^{2} } = 83 }}}$
