the forth one is right

Answer:

Option C.

Step-by-step explanation:

Since f(x) = √(x² + 12x + 36)

g(x) = x³ - 12

We have to solve the expression f(x).g(x)

f(x).g(x) = {√(x² + 12x + 36)}.{x³ - 12} = [√(x + 6)²].(x³-12) = (x + 6)(x³-12)

= [tex]x^{4}+6x^{3}-12x-72[/tex]

which matches with option C.

Therefore option C is the correct option.
