Question

How to find the nature of roots of ax^2+bx+c=0 if a >0 b=0c>0?

Answer 1

use discriminant=0... if its equal to 0 the the roots are real and equal if ≠ 0 then the roots are real and unequal and if <0 then conjugate and imaginary

Answer 2

the roots are imaginary bcoz

b = 0

so eq. is x^2 = -c/a

c and a are positive so x^2 is negative which is not possible.
