Question

if X + 1 divided by x is equal to 5 then the value of x square + 1 by x square is equal to

Answer 1

x + 1/x = 5

On squaring both sides, we get

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

=> x^2 + 1/x^2 + 2 = 25

=> x^2 + 1/x^2 = 23

Answer 2

(x+1)/x=5
squaring both side
(x+1)^2/x^2=25
x^2+2x+1=25x^2
x^2+1=25x^2-2x
x^2+1=x(25x-2)
(x^2+1)/x=25x-2
