Factorise (x-3y)^3+(3y-√3z)^3+(√3z-x)^3 Please answer this fast and correctly

1) Use this rule:

2) Use Multiplication Distributive Property:

3) Simplify to

4) Simplify square root

5) Simplify to

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3

df =

both have same length
