Question

The nature of roots of a quadratic equation is real and equal if:

a. D > 0

b. D < 0​

Answer 1

Step-by-step explanation:

When a, b and c are real numbers, a ≠ 0 and discriminant is zero (i.e., b2 - 4ac = 0), then the roots α and β of the quadratic equation ax2 + bx + c = 0 are real and equal.

Answer 2

Answer:

a. distinct real roots

b. no real roots
