Let

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

be one of the roots of a quadratic equation with real coefficients. Find the other root

x_{2}

of this equation.

x_{2} = 2 + \frac{\sqrt{5}}{2} i

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

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

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