You got it! THAT was obviously too easy. Back to real math! Consider a polynomial F(x) = x2 + x + 41. Let's check its values for a few first integers: F(1) = 43 which is prime. F(2) = 47 which is also prime. Furthermore, F(3) = 53, F(4) = 61, F(5) = 71, F(6) = 83, F(7) = 97, F(8) = 113, F(9) = 131, all of which are prime. Is it right to conclude that F(x) is a prime for all integer x? And if you enough math, you may be able to answer that immediately.
