- 2 x^{2} + 8 x + 6 = 0

x = 2 - 7, x = 2 + 7

Solution steps

- 2 x^{2} + 8 x + 6 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 8 \pm 8 ^{2} - 4 ( - 2 ) \cdot 6}{2 ( - 2 )}

8^{2} - 4 (- 2) \cdot 6 = 47

x_{1, 2} = \frac{- 8 \pm 4 7}{2 ( - 2 )}

Separate the solutions

x_{1} = \frac{- 8 + 4 7}{2 ( - 2 )}, x_{2} = \frac{- 8 - 4 7}{2 ( - 2 )}

x = \frac{- 8 + 4 7}{2 ( - 2 )} : 2 - 7

x = \frac{- 8 - 4 7}{2 ( - 2 )} : 2 + 7

The solutions to the quadratic equation are:

x = 2 - 7, x = 2 + 7
