Hi ,
a³ - 1/a³ - 2a + 2/a
= ( a³ - 1/a³ ) - 2( a - 1/a )
= ( a - 1/a ) ( a² + 1 + 1/a² ) - 2( a - 1/a )
= ( a - 1/a ) ( a² + 1 + 1/a² ) - 2( a - 1/a )
= ( a - 1/a ) [ a² + 1 + 1/a² - 2 ]
= ( a - 1/a ) ( a² - 1 + 1/a² )
I hope this helps you.

a³ - 1/a³ - 2a + 2/a
= ( a³ - 1/a³ ) - 2( a - 1/a )
= ( a - 1/a ) ( a² + 1 + 1/a² ) - 2( a - 1/a )
= ( a - 1/a ) ( a² + 1 + 1/a² ) - 2( a - 1/a )
= ( a - 1/a ) [ a² + 1 + 1/a² - 2 ]
= ( a - 1/a ) ( a² - 1 + 1/a² )
I hope this helps you.
