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

x = \frac{- 1 + 11}{5}, x = - \frac{1 + 11}{5}

Decimal Notation

x = 0.46332 \dots, x = - 0.86332 \dots

Solution steps

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

Solve with the quadratic formula

x_{1, 2} = \frac{- 2 \pm 2 ^{2} - 4 \cdot 5 ( - 2 )}{2 \cdot 5}

2^{2} - 4 \cdot 5 (- 2) = 211

x_{1, 2} = \frac{- 2 \pm 2 11}{2 \cdot 5}

Separate the solutions

x_{1} = \frac{- 2 + 2 11}{2 \cdot 5}, x_{2} = \frac{- 2 - 2 11}{2 \cdot 5}

x = \frac{- 2 + 2 11}{2 \cdot 5} : \frac{- 1 + 11}{5}

x = \frac{- 2 - 2 11}{2 \cdot 5} : - \frac{1 + 11}{5}

The solutions to the quadratic equation are:

x = \frac{- 1 + 11}{5}, x = - \frac{1 + 11}{5}

12 1^{\frac{1}{2}}

7 x^{2} + 10 = 18
