Nájdite hodnoty reálnych koeficientov \(a\), \(b\) a \(c\) tak, aby kvadratická rovnica \[ ax^{2} + bx + c = 0 \] mala komplexné korene \(x_{1, 2} =\pm \mathrm{i}\frac{\sqrt{5}} {3} \).
\(a = 9\text{, }b = 0\text{, }c = 5\)
\(a = 5\text{, }b = 0\text{, }c = 9\)
\(a = 9\text{, }b = 0\text{, }c = -5\)
\(a = 5\text{, }b = 0\text{, }c = -9\)
