Question

x-1/x=8 . find the value of x²-2/x²​

Answer 1

Step-by-step explanation:

$\frac{x - 1}{x} = 8$

$=> x - 1 = 8x$

$=> 7x = - 1$

$=> x = - \frac{1}{7}$

$\frac{ {x}^{2} - 2 }{ {x}^{2} }$

$= \frac{ {( - \frac{1}{7} )}^{2} - 2}{ {( - \frac{1}{7} )}^{2} }$

$= \frac{ \frac{1}{49} - 2}{ \frac{1}{49} }$

$= \frac{1 - 98}{49} \times 49$

$= - 97$

Answer 2

Answer:

x

x−1

=8

= > x - 1 = 8x=>x−1=8x

= > 7x = - 1=>7x=−1

= > x = - \frac{1}{7}=>x=−
