Answer:
5i and -5i
Step-by-step explanation:
Both of these would have to be in the equation for either of them to work, and as the problem already told us that there is only a 3rd root, neither will be our answer.
Have a great day, and feel free to comment with questions!
:)
Imaginary roots come in pairs, so the third root must be a real number. Therefore, neither 5i nor -5i can be the third root.
5t + 9 - 3t + 4
2t + 13
