2 x^{2} + 14 x + 2 = 0

x = \frac{- 7 + 3 5}{2}, x = - \frac{7 + 3 5}{2}

Solution steps

2 x^{2} + 14 x + 2 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 14 \pm 1 4 ^{2} - 4 \cdot 2 \cdot 2}{2 \cdot 2}

1 4^{2} - 4 \cdot 2 \cdot 2 = 65

x_{1, 2} = \frac{- 14 \pm 6 5}{2 \cdot 2}

Separate the solutions

x_{1} = \frac{- 14 + 6 5}{2 \cdot 2}, x_{2} = \frac{- 14 - 6 5}{2 \cdot 2}

x = \frac{- 14 + 6 5}{2 \cdot 2} : \frac{- 7 + 3 5}{2}

x = \frac{- 14 - 6 5}{2 \cdot 2} : - \frac{7 + 3 5}{2}

The solutions to the quadratic equation are:

x = \frac{- 7 + 3 5}{2}, x = - \frac{7 + 3 5}{2}

\frac{4}{5} + \frac{1}{4}

3 x^{2} = - x + 8

4 v^{2} - 4 v - 8

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