Find the complex roots of the following quadratic equation.

9 x^{2} + 4 i = 0

x_{1} = - \frac{\sqrt{2}}{3} + \frac{\sqrt{2}}{3} i, x_{2} = \frac{\sqrt{2}}{3} - \frac{\sqrt{2}}{3} i

x_{1} = \frac{2}{3} i, x_{2} = - \frac{2}{3} i

x_{1} = \frac{\sqrt{2}}{3} + \frac{\sqrt{2}}{3} i, x_{2} = - \frac{\sqrt{2}}{3} - \frac{\sqrt{2}}{3} i

x_{1} = \frac{2}{3}, x_{2} = - \frac{2}{3}
