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

Answer is (b) real and unequal
We know that when discriminant, D>0, the roots of the given quadratic cquation are real and uncqual.
