Question

if x=1/x-5 find x²+1/x²​

Answer 1

I think answer should be 0

Answer 2

Answer:

23 is the answer

Step-by-step explanation:

Given :  

( x + 1 /x ) = 5  

We need to find x² + 1 / x²  

( x + 1 / x )² = (5)²  

= x² + 1 / x² + 2 = 25  

= x² + 1/x² + 2 = 25  

= x² + 1 / x² = 25 – 2  

= x² + 1 / x² =23

Hence x² + 1 / x² = 23
