Answer:
It's easy, but one has to just think about it.
Step-by-step explanation:
x³ +x²+16 is exactly divisible by x.
(Don't tell anyone, I'm now going to divide the polynomial by x)
is an integer.
(whatever the value of x is, we are interested in 16/x).
(which means that 16 should be divisible by x).
Which Implies that all the possible values of x are:-
1, 2, 4, 8 and 16. (Negative versions also should be counted, but as in the question, x is a positive integer)
Therefore, the exact answer is 5.
