Answer 1

Hey !!!!

•°• x³ + y³ + z³ = (x + y + z ) ( x² + y² + z² - xy - yz - x z )

=> multiplied by 2 and also divide 2

then we get

1/2(x + y + z ) 2 ( x² + y² + z² - xy - yz - xz )

1 / 2 ( x + y + z ) {( 2x² + 2y² + 2z² - 2xy - 2yz - 2 xz ) }

=> 1/2 ( x + y + z ) ² {( x² + x² + y² + y² + z² + z² - 2 xy - 2 yz - 2 zx ) }

=> 1/2 ( x + y + z ) ²{ ( x² + y² - 2xy ) ( y² + z² - 2yz ) ( z² + x² - 2xz ) }

=> 1/2 ( x + y + z )² {( x - y )² ( y - z ) ² ( z - x )²} prooved ™
