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 real solutions and one of the solutions is bigger than the other one.

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

b^{2} - 4 a c \neq 0 and a \neq 0

- \frac{b}{2 a} > \frac{\sqrt{b^{2} - 4 a c}}{2 a}

- \frac{b}{2 a} < \frac{\sqrt{b^{2} - 4 a c}}{2 a}
