Answer:
x^2 - 4x + 29 = 0
Step-by-step explanation:
Complex roots occur as conjugate pairs.
So the other root will be 2 - 5i.
First write the equation it in factor form:-
(x - (2 + 5i)) (x - (2 - 5i) = 0
(x - 2 - 5i)(x - 2 + 5i) = 0 Now expand:-
x^2 - 2x + 5ix - 2x + 4 - 10i - 5ix + 10i - 25i^2 = 0
x^2 -2x - 2x + 4 - 25*-1 = 0
x^2 - 4x + 29 = 0 (answer)
