2 x^{2} - x + 9 = 0

x = \frac{1}{4} + i \frac{71}{4}, x = \frac{1}{4} - i \frac{71}{4}

Solution steps

2 x^{2} - x + 9 = 0

Solve with the quadratic formula

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

Simplify

(- 1)^{2} - 4 \cdot 2 \cdot 9 : 71 i

x_{1, 2} = \frac{- ( - 1 ) \pm 71 i}{2 \cdot 2}

Separate the solutions

x_{1} = \frac{- ( - 1 ) + 71 i}{2 \cdot 2}, x_{2} = \frac{- ( - 1 ) - 71 i}{2 \cdot 2}

x = \frac{- ( - 1 ) + 71 i}{2 \cdot 2} : \frac{1}{4} + i \frac{71}{4}

x = \frac{- ( - 1 ) - 71 i}{2 \cdot 2} : \frac{1}{4} - i \frac{71}{4}

The solutions to the quadratic equation are:

x = \frac{1}{4} + i \frac{71}{4}, x = \frac{1}{4} - i \frac{71}{4}
