If one root of the equation

{x^2} + \left( {\mathrm{l} - 3i} \right)x - 2\left( {\mathrm{l} + i} \right) = 0

- \mathrm{l} + i

, then the other root is

View answer and explanation

Correct option: D

2i

Option D (

2i

) is correct because it is the other root of the quadratic equation, found by using the sum of roots property.
