Answer 1

Answer:

( x + 1/x)( x + 1/x - 2)

Step-by-step explanation:

x^2 + 1/x^2 + 2 - 2x -2/x

= ( x + 1/x )^2 -2( x + 1/x ) since x^2 + 1/x^2 + 2 is in the form a^2 + b^2 + 2ab = ( a + b)^2

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

Factorisation done here is by :

=> algebric identity a^2 + b^2 + 2ab = ( a + b) ^2

=> taking out the common term which is x + 1/x
