Put the steps in order to prove the polynomial identity for the square of a trinomial, (x − y — z)². V (x-y-z) (x - y — z)

Question

Put the steps in order to prove the polynomial identity for the square of a trinomial,
(x − y — z)².
<
>
V
(x-y-z) (x - y — z)
(x - y - 2)²
x² - xy - xz - xy + y² + yz − xz+yz+z²
x² + y² + x² - 2xy - 2xz+ 2yz
