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

x = \frac{- 1 + 19}{9}, x = - \frac{1 + 19}{9}

Decimal Notation

x = 0.37321 \dots, x = - 0.59543 \dots

Solution steps

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

Solve with the quadratic formula

x_{1, 2} = \frac{- 2 \pm 2 ^{2} - 4 \cdot 9 ( - 2 )}{2 \cdot 9}

2^{2} - 4 \cdot 9 (- 2) = 219

x_{1, 2} = \frac{- 2 \pm 2 19}{2 \cdot 9}

Separate the solutions

x_{1} = \frac{- 2 + 2 19}{2 \cdot 9}, x_{2} = \frac{- 2 - 2 19}{2 \cdot 9}

x = \frac{- 2 + 2 19}{2 \cdot 9} : \frac{- 1 + 19}{9}

x = \frac{- 2 - 2 19}{2 \cdot 9} : - \frac{1 + 19}{9}

The solutions to the quadratic equation are:

x = \frac{- 1 + 19}{9}, x = - \frac{1 + 19}{9}

9 x^{2} = 5

x, 4 x^{2} - 8 x + 1 = 0

4 x^{2} + 8 x - 1 = 0

5 x^{2} - 15 x - 30 = 0

a^{2} + 7 a - 18 = 0
