Given that the equation

{z^2} + \left( {p + iq} \right)z + r + \,\,is = 0

where

p,\;q,\;r,\;s\;

are real and non-zero roots, then

View answer and explanation

Correct option: D

pqs = {s^2} + {q^2}r

Option D (

pqs = {s^2} + {q^2}r

) is correct because substituting a real root into the equation and separating real and imaginary parts leads to this relationship.
