Which of the following equations has no real roots?


For the quadratic equation to have no real roots, the discriminant value should be negative i.e.,

D = b2 - 4ac = 0


A. Given,


D = b2 - 4ac = 0




Hence, the roots are imaginary.


B. Given,


D = b2 - 4ac = 0




Hence, the roots are real and distinct.


C. Given,


D = b2 - 4ac = 0




Hence, the roots are real and distinct.


D. Given,


D = b2 - 4ac = 0




Hence, the roots are real and equal.
