Answer 1

Answer:

answer = 3 as x^2+1=10. x^2=9 . x=✓9. x=3

Answer 2

x = 3

Step-by-step explanation:

$\frac{ {x}^{2} + 1 }{ {x}^{2} - 1 } = \frac{10}{8} \\ \\ Do \: cross \: multiplication \: \\ \\ 8( {x}^{2} + 1) = 10( {x}^{2} - 1) \\ \\ 8 {x}^{2} + 8 = 10 {x}^{2} - 10 \\ \\ Bring \: {x}^{2} \: terms \: to \: right \: side \: \\ \\ 8 {x}^{2} - 10 {x}^{2} = - 10 - 8 \\ \\ - 2 {x}^{2} = - 18 \\ \\ {x}^{2} = \frac{ - 18}{ - 2} \\ \\ {x}^{2} = 9 \\ \\ x = \sqrt{9} = 3$
