Question

x + 1 by x equal to 3 then x square + 1 by x square equal to what

Answer 1

$x + \frac{1}{x} = 3 \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: {x}^{2} + \frac{1}{ {x}^{2} } = {3}^{2} = 9$

Answer 2

x+1/x=3
(x+1/x)Sq =(3)Sq
x Sq +1/x Sq +2=9
x Sq +1/xsq =9-2
x Sq +1/xsq=7
