(x^3 + y^3 + z^3) - 3xyz = ( x+y+z) (x^2 + y^2 + z^2 -xy -yz- zx ).........(1)
But, we have been given that
( x^2 + y^2 + z^2) = xy + yz + zx ..........(2)
Put the above result in equation .....(1)
We get,
(x^3 + y^3 + z^3) - 3xyz = (x+y+z) ( xy + yz + zx - ( xy + yz+ zx )
So,
(x^3 + y^3 + z^3) = 3xyz
Hence, proved
