Question

Answer this question
Find the nature of the roots of the quadratic equation ax^2+2bx+c=0 if abc are in AP.

Answer 1

So it depends upon the value of difference in a, b, c

Probably it is >1 so roots will be distinct and real
But in case d=0 then they are real but equal
And in case d<1 the are imaginary

Answer 2

the answer depends upon the value of d
as the discriminant is coming 4d^2
