Q. If $x_{1},x_{2},x_{3}$ are distinct roots of the equation $ax^{2} + bx + c = 0$, then
A) $a = b = 0,c \in R$
B) $a = c = 0,b \in R$
C) $b^{2} - 4ac \geq 0$
D) $a = b = c = 0$
Explanation
(d)
Since, quadratic equation $ax^{2} + bx + c = 0$ has three distinct roots. So, it must be identity. So, $a = b = c = 0$.
