- 8 x^{2} - x - 2 = 0

x = - \frac{1}{16} - i \frac{3 7}{16}, x = - \frac{1}{16} + i \frac{3 7}{16}

Solution steps

- 8 x^{2} - x - 2 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 1 ) \pm ( - 1 ) ^{2} - 4 ( - 8 ) ( - 2 )}{2 ( - 8 )}

Simplify

(- 1)^{2} - 4 (- 8) (- 2) : 37 i

x_{1, 2} = \frac{- ( - 1 ) \pm 3 7 i}{2 ( - 8 )}

Separate the solutions

x_{1} = \frac{- ( - 1 ) + 3 7 i}{2 ( - 8 )}, x_{2} = \frac{- ( - 1 ) - 3 7 i}{2 ( - 8 )}

x = \frac{- ( - 1 ) + 3 7 i}{2 ( - 8 )} : - \frac{1}{16} - i \frac{3 7}{16}

x = \frac{- ( - 1 ) - 3 7 i}{2 ( - 8 )} : - \frac{1}{16} + i \frac{3 7}{16}

The solutions to the quadratic equation are:

x = - \frac{1}{16} - i \frac{3 7}{16}, x = - \frac{1}{16} + i \frac{3 7}{16}

12 x^{2} + 6 x + 11 = 0

35 k^{2} - 22 k + 7 = 4

x, f = k - 5 k + 1 x^{2} - 20

6 x^{2} + 24 x - 30 = 810

x^{2} - 15 x = 11 - 5 x
