x^{2} + 10 x + 30 = 0

x = - 5 + 5 i, x = - 5 - 5 i

Solution steps

x^{2} + 10 x + 30 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 10 \pm 1 0 ^{2} - 4 \cdot 1 \cdot 30}{2 \cdot 1}

Simplify

1 0^{2} - 4 \cdot 1 \cdot 30 : 25 i

x_{1, 2} = \frac{- 10 \pm 2 5 i}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 10 + 2 5 i}{2 \cdot 1}, x_{2} = \frac{- 10 - 2 5 i}{2 \cdot 1}

x = \frac{- 10 + 2 5 i}{2 \cdot 1} : - 5 + 5 i

x = \frac{- 10 - 2 5 i}{2 \cdot 1} : - 5 - 5 i

The solutions to the quadratic equation are:

x = - 5 + 5 i, x = - 5 - 5 i

(2 - 4 i) (2 + 4 i)

x^{2} + 8 x - 65 = x - 5

5 \cdot 4 \cdot 3 \cdot 2 \cdot 1

r - 7 = - 3

\frac{3 ^{- 1}}{( - 5 ) ^{0}}
