Which of the given quadratic equations has the roots \( x_1 = 2 + \mathrm{i} \) and \( x_2 = 1 - 3\,\mathrm{i} \)?
\( x^2 - (3 - 2\,\mathrm{i})x + 5 - 5\,\mathrm{i} = 0 \)
\(x^2 + (3 - 2\,\mathrm{i})x + 5 - 5\,\mathrm{i} = 0 \)
\( x^2 - (3 + 2\,\mathrm{i})x + 5 - 5\,\mathrm{i} = 0 \)
\( x^2 + (3 + 2\,\mathrm{i})x + 5 - 5\,\mathrm{i} = 0 \)
