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 \(a\), \(b\), \(c\) does not have a real solution.
\((b^{2} - 4ac < 0\text{ and }a\not = 0)\text{ or }(a = b = 0\text{ and }c\not = 0)\)
\(b^{2} - 4ac < 0\)
\(b^{2} - 4ac < 0\text{ and }a\not = 0\)
\((b^{2} - 4ac < 0\text{ and }a\not = 0)\text{ or }(ab = 0\text{ and }c\not = 0)\)
