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

x = - \frac{1}{3}, x = - \frac{2}{3}

Decimal Notation

x = - 0.33333 \dots, x = - 0.66666 \dots

Solution steps

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

Solve with the quadratic formula

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

9^{2} - 4 \cdot 9 \cdot 2 = 3

x_{1, 2} = \frac{- 9 \pm 3}{2 \cdot 9}

Separate the solutions

x_{1} = \frac{- 9 + 3}{2 \cdot 9}, x_{2} = \frac{- 9 - 3}{2 \cdot 9}

x = \frac{- 9 + 3}{2 \cdot 9} : - \frac{1}{3}

x = \frac{- 9 - 3}{2 \cdot 9} : - \frac{2}{3}

The solutions to the quadratic equation are:

x = - \frac{1}{3}, x = - \frac{2}{3}
