Answer 2

Hello friend
__________________________________________________________

x³ + y³       = ( x + y ) ( x² - xy + y² )
= ( x + y )³ = x³ + y³ + 3xy ( x + y )
= x³ + y³    = ( x + y )³ - 3xy ( x + y )
                 = ( x + y ) [ ( x + y )² - 3xyz ]
                 = ( x + y ) ( x² + y² + 2xy - 3xy )
                 = ( x + y ) ( x² + y² - xy )
                 = ( x + y ) ( x² - xy + y² )
