Answer 2

Answer:

(3x+y+z)(9x ^2  +y^2+z ^2  −3xy−yz−3zx).

Step-by-step explanation:

27x^3  + y^3  +z^3  −9xyz

=(3x)^3  +y^3  +z^  3  −9xyz

=(3x)^3+y^3  +z^3  −3×3x×y×z

using identity

a^3  +b^3  +c^3  −3abc = (a+b+c)(a^2 +b^ 2+c^2−ab−bc−ca)

Putting a =  3x,   b = y,   c = z

= (3x+y+z)(9x ^2  +y^2+z ^2  −3xy−yz−3zx).
