- x^{2} + 6 x - 30 = 0

x = 3 - 21 i, x = 3 + 21 i

Solution steps

- x^{2} + 6 x - 30 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 6 \pm 6 ^{2} - 4 ( - 1 ) ( - 30 )}{2 ( - 1 )}

Simplify

6^{2} - 4 (- 1) (- 30) : 221 i

x_{1, 2} = \frac{- 6 \pm 2 21 i}{2 ( - 1 )}

Separate the solutions

x_{1} = \frac{- 6 + 2 21 i}{2 ( - 1 )}, x_{2} = \frac{- 6 - 2 21 i}{2 ( - 1 )}

x = \frac{- 6 + 2 21 i}{2 ( - 1 )} : 3 - 21 i

x = \frac{- 6 - 2 21 i}{2 ( - 1 )} : 3 + 21 i

The solutions to the quadratic equation are:

x = 3 - 21 i, x = 3 + 21 i

\frac{2 π}{( \frac{π}{3} )}
