Answer:

-a^2 - a + 12

Explanation:

You only need to find the products of the first and last terms to determine the correct answer:

(-a)(a) = -a^2

(3)(4) = 12

You're looking for an expression with -1 as the leading coefficient and +12 as the constant. There is only one choice like that:

-a^2 - a + 12
