125x³ + y³
(5y)³ + (y)³
We know that,
( a³ + b³ ) = ( a + b ) ( a² - ab + b² )
So,
( 5x)³ + (y)³ = ( 5x + y ) { (5x)² - 5XY + Y² }
=> ( 5x + Y ) ( 25x² - 5XY + Y² )
(5y)³ + (y)³
We know that,
( a³ + b³ ) = ( a + b ) ( a² - ab + b² )
So,
( 5x)³ + (y)³ = ( 5x + y ) { (5x)² - 5XY + Y² }
=> ( 5x + Y ) ( 25x² - 5XY + Y² )
