Find the condition which is equivalent to the fact that the equation
\(ax^{2} + bx + c = 0\) with
\(x\in \mathbb{R}\) and real
coefficients \(a\),
\(b\),
\(c\)
has a solution in a form of a pair of two opposite real nonzero numbers.
\(\frac{c}
{a} < 0\text{ and }b = 0\)
\(- \frac{b}
{2a} = 0\)
\(b^{2} = 4ac\text{ and }a\not = 0\)
\(b^{2} = 4ac\text{ and }a\not = 0\text{ and }c\not = 0\)
