Step-by-step explanation:
1. The student is wrong because imaginary roots always occur in conjugate pairs.
So -4i cannot be the only imaginary root. It has to be accompanied by 4i also.
2. So the 2 roots can be 4i and -4i.
therefore the equation can be
(x - 4i)(x + 4i) = 0
+ 16 = 0
N+d=48
n+d=4.40
am not sure of the equation tho
