Question

Quadratic eqn ax²+ bx + c = 0 has equal roots if A)b - 4ac < 0 B)b - 4ac > 0 C)b - 4ac = 0 D)b - 4ac = 1

Quizplus · Accepted Answer

For a quadratic equation $ax^2 + bx + c = 0$, the condition for it to have equal roots is given by the discriminant $b^2 - 4ac = 0$. This ensures that the quadratic equation has one real root (or two equal real roots).
