(x – 2y – z) (x2 + 4y2 + z2 + 2xy + zx – 2yz)

= [x + (-2y) + (-z)] [(x)2 + (-2y)2 + (-z)2 – (x) (-2y) – (-2y) (-z) – (-z) (x)]

= (a + b + c) (a2 + b2 + c2 – ab – bc – ca)

= a3 + b3 + c3 – 3abc

Where x = a, (-2y) = b and (-z) = c

(x – 2y – z) (x2 + 4y2 + z2 + 2xy + zx – 2yz)

= (x)3 + (-2y)3 + (-z)3 – 3 (x) (-2y) (-z)

= x3 – 8y3 – z3 – 6xyz.
