Ответ:
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
