Answer 2

${\huge{\gray{\underline{\mathbb{\red{Ans}{\orange{wer}{\blue{:-} }}}}}}}$

$\frac{ x - 1}{x} = 4 \\ x - 1 = 4x \\ - 1 = 4x - x \\ - 1 = 3x \\ x = \frac{ - 1}{3}$

then put the value of x

soo

$\frac{ {x}^{2} + 1}{ {x}^{2} + 2 } \\ = \frac{ {\frac{ - 1}{3}}^{2} + 1 }{ { \frac{ - 1}{3} }^{2} + 2} \\ = \frac{\frac{1}{9} + 1}{ \frac{1}{9} + 2 } \\ = \frac{ \frac{10}{9} }{ \frac{11}{9} }$

hope it will help you
