- 7 x^{2} + 4 x - 2 = 0

x = \frac{2}{7} - i \frac{10}{7}, x = \frac{2}{7} + i \frac{10}{7}

Solution steps

- 7 x^{2} + 4 x - 2 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 4 \pm 4 ^{2} - 4 ( - 7 ) ( - 2 )}{2 ( - 7 )}

Simplify

4^{2} - 4 (- 7) (- 2) : 210 i

x_{1, 2} = \frac{- 4 \pm 2 10 i}{2 ( - 7 )}

Separate the solutions

x_{1} = \frac{- 4 + 2 10 i}{2 ( - 7 )}, x_{2} = \frac{- 4 - 2 10 i}{2 ( - 7 )}

x = \frac{- 4 + 2 10 i}{2 ( - 7 )} : \frac{2}{7} - i \frac{10}{7}

x = \frac{- 4 - 2 10 i}{2 ( - 7 )} : \frac{2}{7} + i \frac{10}{7}

The solutions to the quadratic equation are:

x = \frac{2}{7} - i \frac{10}{7}, x = \frac{2}{7} + i \frac{10}{7}
