x^{2} + 8 x + 65 = 0

x = - 4 + 7 i, x = - 4 - 7 i

Solution steps

x^{2} + 8 x + 65 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 8 \pm 8 ^{2} - 4 \cdot 1 \cdot 65}{2 \cdot 1}

Simplify

8^{2} - 4 \cdot 1 \cdot 65 : 14 i

x_{1, 2} = \frac{- 8 \pm 14 i}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 8 + 14 i}{2 \cdot 1}, x_{2} = \frac{- 8 - 14 i}{2 \cdot 1}

x = \frac{- 8 + 14 i}{2 \cdot 1} : - 4 + 7 i

x = \frac{- 8 - 14 i}{2 \cdot 1} : - 4 - 7 i

The solutions to the quadratic equation are:

x = - 4 + 7 i, x = - 4 - 7 i
