x^{2} + x + 9 = 0

x = - \frac{1}{2} + i \frac{35}{2}, x = - \frac{1}{2} - i \frac{35}{2}

Solution steps

x^{2} + x + 9 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 1 \pm 1 ^{2} - 4 \cdot 1 \cdot 9}{2 \cdot 1}

Simplify

1^{2} - 4 \cdot 1 \cdot 9 : 35 i

x_{1, 2} = \frac{- 1 \pm 35 i}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 1 + 35 i}{2 \cdot 1}, x_{2} = \frac{- 1 - 35 i}{2 \cdot 1}

x = \frac{- 1 + 35 i}{2 \cdot 1} : - \frac{1}{2} + i \frac{35}{2}

x = \frac{- 1 - 35 i}{2 \cdot 1} : - \frac{1}{2} - i \frac{35}{2}

The solutions to the quadratic equation are:

x = - \frac{1}{2} + i \frac{35}{2}, x = - \frac{1}{2} - i \frac{35}{2}

25 x^{2} - 60 x + 36
