5 x^{2} + 10 x + 8 = 0

x = - 1 + i \frac{3}{5}, x = - 1 - i \frac{3}{5}

Solution steps

5 x^{2} + 10 x + 8 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 10 \pm 1 0 ^{2} - 4 \cdot 5 \cdot 8}{2 \cdot 5}

Simplify

1 0^{2} - 4 \cdot 5 \cdot 8 : 215 i

x_{1, 2} = \frac{- 10 \pm 2 15 i}{2 \cdot 5}

Separate the solutions

x_{1} = \frac{- 10 + 2 15 i}{2 \cdot 5}, x_{2} = \frac{- 10 - 2 15 i}{2 \cdot 5}

x = \frac{- 10 + 2 15 i}{2 \cdot 5} : - 1 + i \frac{3}{5}

x = \frac{- 10 - 2 15 i}{2 \cdot 5} : - 1 - i \frac{3}{5}

The solutions to the quadratic equation are:

x = - 1 + i \frac{3}{5}, x = - 1 - i \frac{3}{5}

3 x^{2} + 10 x + 73 = 0

3 x^{2} - 18 x - 42 = 6

(15 - 2 x) (6 - 2 x) = 22

x^{2} + 8 x - 21 = 0

5 x^{2} = 24
