Which binomial is a factor of the quadratic trinomial x2 - 7x + 12? A. (x + 2) B. (x - 6) C. (x + 3) D. (x - 4)

D

Step-by-step explanation:

To factor a quadratic you need to think about what adds up to the b coefficient (the number in front of b) and multiplies to the constant. 3 and 4 do these, but you also know that you have - 7 instead of positive 7. A negative times a negative is equal to a positive, which you can do (x-3) (x-4) to equal your quadratic trinomial.
