Answer:
C: x^4+6x^3-12x-72
Step-by-step explanation:
For the function : f(x)=√x^2+12x+36
It can be factorized to
f(x)=√(x+6)²
=x+6
f(x)*g(x)
=(x+6)(x^3-12)
Expand the brackets
=x^4-12x+6x^3-72
rearrange the numbers
x^4+6x^3-12x-72
Add 110 to both sides so you get -240
then divide it by 16 so you get x = -15
Check
-350 = -110+16(-15)
-350 = -110 - 240
-350 = -350

Since 19 is a prime number (a number that only has 2 factors: one and itself), 19/36 is the simplest form.
9+6543 is 6,552 then you times it with 7 which is 45,810
