Question

The quadratic equation has one x-intercept. The discriminant condition ensures real roots. Thus the correct option is:

a. A
b. B
c. C
d. D

Answer 1

The correct option is A.

Step-by-step explanation:

In quadratic equations, the discriminant (b^2 - 4ac) determines the nature of the roots. If the discriminant is positive, the equation has two distinct real roots. If the discriminant is zero, the equation has one real root. And if the discriminant is negative, the equation has two complex roots.

In this case, since the equation has only one x-intercept, it implies that the discriminant is zero. Therefore, the correct option is A.
