5 x^{2} + 10 x + 7 = 0

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

Solution steps

5 x^{2} + 10 x + 7 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 10 \pm 1 0 ^{2} - 4 \cdot 5 \cdot 7}{2 \cdot 5}

Simplify

1 0^{2} - 4 \cdot 5 \cdot 7 : 210 i

x_{1, 2} = \frac{- 10 \pm 2 10 i}{2 \cdot 5}

Separate the solutions

x_{1} = \frac{- 10 + 2 10 i}{2 \cdot 5}, x_{2} = \frac{- 10 - 2 10 i}{2 \cdot 5}

x = \frac{- 10 + 2 10 i}{2 \cdot 5} : - 1 + i \frac{2}{5}

x = \frac{- 10 - 2 10 i}{2 \cdot 5} : - 1 - i \frac{2}{5}

The solutions to the quadratic equation are:

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