{x_1},{x_2},{x_3}

are distinct roots of the equation

a{x^2} + bx + c = 0

, then

View answer and explanation

Correct option: D

a = b = c = 0

Option D (

a = b = c = 0

) is correct because a quadratic equation cannot have three distinct roots unless it is an identity, which requires all coefficients to be zero.
