Step-by-step explanation:

$3(x - 2y) + 3(2y - z) - 3(x - z) \\ = 3x - 6y + 6y - 3z - 3x + 3z \\ = 0$

Everything is cancelled out .!!!

Answer 2

Answer:

x^3-2y^3-3×X×2y (x-2y)+2y^3-z^3-3×2y×z(2y-z)-x^3-z^3-3×Xxz(x-z)

x^3 - 8y^3-6x^2y-12xy^2+8y^3-z^3-12y^2z-6yz^2-x^3-z^33x^2z-3xz^2

by cutting +/- sign you can find answer
