Find the solution set of the following equation in the set of complex numbers.

x^{3} + 27 = 0

{- 3; \frac{3}{2} - i \frac{3 \sqrt{3}}{2}; \frac{3}{2} + i \frac{3 \sqrt{3}}{2}}

{- 3; - \frac{3}{2} + i \frac{3 \sqrt{3}}{2}; - \frac{3}{2} - i \frac{3 \sqrt{3}}{2}}

{- 3; \frac{3}{2} - i \frac{\sqrt{3}}{2}; \frac{3}{2} + i \frac{\sqrt{3}}{2}}

{- 3; - \frac{3}{2} + i \frac{\sqrt{3}}{2}; - \frac{3}{2} - i \frac{\sqrt{3}}{2}}
