Answer 1

Answer:

If the roots of quadratic equation is real and distinct then "d" should be greater than zero or a positive integer.

Step-by-step explanation:

For a quadratic equations ax² + bx + c = 0

D = b² - 4ac

D is called discriminant.

Nature of roots on the basis of discriminant (D):

1. D > 0 [D is a postive integer]

Both the roots are real and distinct.

2. D = 0 [D is zero]

Both the roots are real and equal.

3. D < 0 [D is a negative integer]

Both the roots are imaginary.
