Objective Questions (MCQ)

In the equation $a x^{2}+b x+c=0$, it is given that $D=\left(b^{2}-4 a c\right)>0$. Then, the roots of the equation are

(a) real and equal                                                        (b) real and unequal
(c) imaginary                                                              (d) none of these



We know that when discriminant, $D>0$, the roots of the given quadratic equation are real and unequal.

Hence, the correct answer is option B.
