Heya !!
X³ - 2X² - X + 2
=> X² ( X - 2 ) - 1 ( X - 2 )
=> ( X - 2 ) ( X² - 1 )
=> ( X - 2 ) { (X)² - (1)² }
=> ( X - 2 ) ( X + 1 ) ( X - 1 ) [ Answer ]

Hey !
x³ - 2x² - x + 2
x² ( x - 2 ) - 1 ( x - 2 )
( x - 2 ) ( x² - 1 )
( x - 2 ) ( x² - 1² )
we know that ( a² - b² ) = ( a + b ) ( a - b ).
so,
( x - 2 ) ( x² - 1² )
( x - 2 ) ( x - 1 ) ( x + 1 ).
x³ - 2x² - x + 2
x² ( x - 2 ) - 1 ( x - 2 )
( x - 2 ) ( x² - 1 )
( x - 2 ) ( x² - 1² )
we know that ( a² - b² ) = ( a + b ) ( a - b ).
so,
( x - 2 ) ( x² - 1² )
( x - 2 ) ( x - 1 ) ( x + 1 ).
