Question

The roots of ax^2 + bx + c= 0 , a ≠ 0 are real , if b^2 - 4ac is 1 point a) =0 b) >=0 c) < 0 d) none of these

Answer 1

Answer:

The roots of ax^2 + bx + c= 0 , a ≠ 0 are real , if b^2 - 4ac is b) >=0

Since the condition for all roots of an equation to be equal in a quadratic equation is

Discriminant >= 0
