It is prime only for x = -4 and x = -7. For any other integer x, the value of this expression is not prime.
First of all, a Prime number is a number only divisible by two positive numbers: 1 and itself.
Factoring out the expression, we have:
x² + 11x + 30 = (x+5) (x+6)
So the result is divisible by at least two numbers, (x+5) and (x+6). The only cases where this lead to a prime number are the ones where one of the factors is 1 and the other isn't 0 (since 0 is not prime):
x = -4 => (-4 + 5) (-4 + 6) = 2
x = -7 => (-7 + 5) (-7 + 6) = (-2) (-1) = 2
If x must be a counting number, then there's no x for which the expression value is prime.
