- 5 x^{2} - 2 x - 1 = 0

x = - \frac{1}{5} - i \frac{2}{5}, x = - \frac{1}{5} + i \frac{2}{5}

Solution steps

- 5 x^{2} - 2 x - 1 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 2 ) \pm ( - 2 ) ^{2} - 4 ( - 5 ) ( - 1 )}{2 ( - 5 )}

Simplify

(- 2)^{2} - 4 (- 5) (- 1) : 4 i

x_{1, 2} = \frac{- ( - 2 ) \pm 4 i}{2 ( - 5 )}

Separate the solutions

x_{1} = \frac{- ( - 2 ) + 4 i}{2 ( - 5 )}, x_{2} = \frac{- ( - 2 ) - 4 i}{2 ( - 5 )}

x = \frac{- ( - 2 ) + 4 i}{2 ( - 5 )} : - \frac{1}{5} - i \frac{2}{5}

x = \frac{- ( - 2 ) - 4 i}{2 ( - 5 )} : - \frac{1}{5} + i \frac{2}{5}

The solutions to the quadratic equation are:

x = - \frac{1}{5} - i \frac{2}{5}, x = - \frac{1}{5} + i \frac{2}{5}

15 c + 12 (- 16 c - 11)

x - 2 > 4 - x

n^{2} + 10 n - 45 = 0

3 x^{2} - 6 x = 24
