Question

if x - 1 by x is equal to 5,then find the value of xpower by 2 +1 by x power by 2​

Answer 1

Answer:

Step-by-step explanation:

x + 1 /x ) = 5

We need to find X2+ 1 / x2

( x + 1 / x )2 = 25

= x2 + 1 / x2 + 2 (x)(1)(1/x) =25

= x2 + 1/x2 + 2 = 25

= X2 + 1 / x2 = 25 – 2

= X2+ 1 / x2=23

Hence X2+ 1 / x2= 23

Hope it helps you ✌️

Answer 2

x-1/x=5

x-1/x=5then x=-1/4

x-1/x=5then x=-1/4=>x^2+1/x^2

x-1/x=5then x=-1/4=>x^2+1/x^2=>17/16*17

x-1/x=5then x=-1/4=>x^2+1/x^2=>17/16*17=>17
