    Zhenghao is correct

    Step-by-step explanation:

    We have that:

    (2x+3) (x + 4) = x² + 7x + 12

    The only two factors of x² + 7x + 12 different from 1,-1 and and itself are (2x+3) and (x + 4)

    If Hafsana says that (x + 3) is a factor of x² + 7 + 12, He or she is not correct.

    If Zhenghao says that x² + 7x + 12 is divisible by 2x + 3, He or she is correct because (2x + 3) is a factor of x² + 7x + 12
