For the equation

\frac{1}{{x + a}} - \frac{1}{{x + b}} = \frac{1}{{x + c}}

, if the product of the roots is zero, then the sum of the roots is

View answer and explanation

Correct option: D

- \frac{{2bc}}{{b + c}}

Option D (

\frac{{ - 2bc}}{{b + c}}

) is correct because solving the equation and using the condition that the product of roots is zero leads to the given sum of roots.
