D Correct answer
Explanation

Factoring x^2 - 7x + 12 = 0 gives (x - 3)(x - 4) = 0. The roots are 3 and 4.

AI explanation

By applying the factoring method to x^2 - 7x + 12 = 0, we identify two numbers that multiply to 12 and add up to -7. These numbers are -3 and -4, allowing us to write the equation as (x - 3)(x - 4) = 0. Setting each factor to zero reveals the roots of the equation are 3 and 4.
