Find the condition which is equivalent to the fact that the equation

a x^{2} + b x + c = 0

with

x \in R

and real coefficients

a

,

b

,

c

has two solutions and one of the solutions is a reciprocal value of the second solution.

b^{2} - 4 a c > 0 and \frac{c}{a} = 1

b^{2} - 4 a c > 0 and a = c

b^{2} - 4 a c > 0 and \frac{c}{a} = - 1

b^{2} - 4 a c > 0 and a = - c
