Answer 1

Answer:

under root 29 , + or - 5

Step-by-step explanation:

Given x² + 1 / x² = 27

( x + 1 / x ) ² = x² + 1 / x² + 2x( 1 / x )

( x + 1/ x ) ² = 27 + 2 ( x × 1 / x = 1 )

( x + 1 / x ) = under root 29

( x - 1 /x )² = x² + 1/x² - 2x × 1/x

substitute values you get x - 1/ x value

Hope you get it
