Hii its tom85

RHS

1/2(x + y + z) [x^2 + y^2 -2xy + y^2 + z^2 - 2yz + z^2 + x^2 - 2zx]

(x+y+z)(x^2 +y^2 + z^2 - xy - yz -zx)

x^3 + ^y^3 +Z^3 + xy^2 + xz^2 + yx^2 + yz^2 + zx^2 +zy^2 - xyz - xyz - xyz - xy^2 - xz^2 - yx^2 - yz^2 - zx^2 - yx^2

x^3 + y^3 + z^3 -3xyz

LHS

__________/\_________☹️

hope it may helps you
