Does anyone know this answer

(x + 2)(x + 9).

You first have to see if there is a common factor, which there is not for this question. A shortcut would be to see what multiples of 18(in this case) add up to be 11(in this case). Since it is x^2, it only works when there is no coefficient in front of the variable. This is how you get the answer, if it makes sense. Make sure you also check your work by multiplying them to see if they match the question. Hope this helps!
