Answer:
Explanation:
The question is a bit ambiguous. Are A B C D and F positive? It says they are prime which is good. I'm going to assume that they are all > 0 but that may not be a valid assumption. I'm not sure that numbers < 0 cannot be prime. Looking it up, I find that the assumption is correct. If they are prime, they are greater than 0.
That says quite a bit.
The factors of f are 1 and f.
The first one is possible x + 1 could be a factor because it will come x = - 1
x + f could be a factor.
Because you will push through x = - f
The only 2 I can guarantee are the two I have given. Even though I have given 2, and someone else came along and gave a different answer, I would defer to what they said.
