x^{2} - x + 18 = 0

x = \frac{1}{2} + i \frac{71}{2}, x = \frac{1}{2} - i \frac{71}{2}

Solution steps

x^{2} - x + 18 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 1 ) \pm ( - 1 ) ^{2} - 4 \cdot 1 \cdot 18}{2 \cdot 1}

Simplify

(- 1)^{2} - 4 \cdot 1 \cdot 18 : 71 i

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

Separate the solutions

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

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

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

The solutions to the quadratic equation are:

x = \frac{1}{2} + i \frac{71}{2}, x = \frac{1}{2} - i \frac{71}{2}

u^{2} + u = 0

3 a^{2} = 27

(2 x - 2)^{2} = - 2 (x - \frac{3}{4})^{2} + \frac{9}{8}

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

s^{2} + 100 = 0
