Answer 1

Heya

_______________________________

GOOD MORNING



Let x = 1 , y = 0 And z = -1

L.H.S

=>

(1)³ + (0)³ + (-1)³ -3(1)(0)(-1)

=>

1 -1 - 0

=>

0

R.H.S

=>

1/2 ( 1 + 0 -1 ) { ( 1 -0 )² + ( 0 +1 )²+ (-1 -1 )²

=>

0× { 1 + 1 -2 }

=>

0 × { 2 - 2 }

=>

0 × { 0 }

=>

0

L.H.S = R.H.S

Hence, verified
