But x must be a natural number, so the answer is

.
Answer:
f= x^2+4x−12
/x
Step-by-step explanation:
Step 1: Divide both sides by x.
fx
/x = x^2+4x−12
/x
f= x^2+4x−12
/x
Dividing 2 into 4 you would get 2 and dividing it into 9 you would get 4 since you can't divide it into 9 so when you subtract that (9-8) you would get 1 you place a decimal and bring down a zero to get 10 then you would get 5 the answer would be 248.5
The first time is 4 over 5 and the second time is 1 over 5
