Question

x+1divided by x=4 find x²+1 divided by x²​

Answer 1

given x+1/x=4

then x=1/3

substituting x=1/3

in x²+1/x²

we get 10

Answer 2

Step-by-step explanation:

$given \\ \frac{(x + 1)}{x} = 4 \\ = > x + 1 = 4x = > 4x - x = 1 \\ = > 3x = 1 = > x = \frac{1}{3} \\ now \\ \frac{( {x}^{2} + 1) }{ {x}^{2} } = \frac{ ({ \frac{1}{3}) }^{2} + 1 }{ ({ \frac{1}{3}) }^{2}} \\ = > \frac{ \frac{1}{9} + 1 }{ \frac{1}{9} } = \frac{ \frac{10}{9} }{ \frac{1}{9} } = \frac{10}{9} \times 9 \\ = > 10$
