Answer 2

Hi ,

********************************

We know the algebraic identity ,

a³ + b³ + c³ - 3abc

= ( a + b + c ) [ a² + b² + c² - ab - bc - ca ]

**********************************
Now ,

27x³ + y³ + z³ - 9xyz

= ( 3x )³ + y³ + z³ - 3 × 3x × y × z

= ( 3x + y + z ) [ (3x )² + y² + z² - ( 3x )y - yz - z ( 3x ) ]

= ( 3x + y + z ) [ 9x² + y² +z² - 3xy -yz - 3zx]

I hope this helps you.
