Rovnice \(x^{2} - 2\mathrm{i}x + q = 0\) má
jeden kořen \(x_{1} = 1 + 2\mathrm{i}\). Najděte
druhý kořen \(x_{2}\)
a koeficient \(q\in \mathbb{C}\).
\(x_{2} = -1,\ q = -1 - 2\mathrm{i}\)
\(x_{2} = -1 - 4\mathrm{i},\ q = 9 - 6\mathrm{i}\)
\(x_{2} = 1 - 4\mathrm{i},\ q = 7 - 4\mathrm{i}\)
\(x_{2} = 1,\ q = -1 - 2\mathrm{i}\)
\(x_{2} = -1,\ q = 1 + 2\mathrm{i}\)
