Answer 2

Given Equation is x^2 + 1/x^2 = 27.


(1) It can be written as x^2 + 1/x^2 - 2 = 25

                                     (x - 1/x)^2 = 25

                                     $(x - \frac{1}{x} ) = 5$



(2) It can be written as

x^2 + 1/x^2 + 2 = 29

(x + 1/x)^2 = 29

$x + \frac{1}{x} = \sqrt{29}$


Hope this helps!
