Find the complex roots of the following quadratic equation.

2 x^{2} + 5 i = 0

x_{1} = - \frac{\sqrt{5}}{2} + \frac{\sqrt{5}}{2} i, x_{2} = \frac{\sqrt{5}}{2} - \frac{\sqrt{5}}{2} i

x_{1} = \frac{\sqrt{5}}{2} + \frac{\sqrt{5}}{2} i, x_{2} = - \frac{\sqrt{5}}{2} - \frac{\sqrt{5}}{2} i

x_{1} = \frac{\sqrt{5}}{2} i, x_{2} = - \frac{\sqrt{5}}{2} i

x_{1} = - \frac{\sqrt{5}}{2}, x_{2} = \frac{\sqrt{5}}{2}
