9 x^{2} + 3 x - 1 = 0

x = \frac{- 1 + 5}{6}, x = - \frac{1 + 5}{6}

Decimal Notation

x = 0.20601 \dots, x = - 0.53934 \dots

Solution steps

9 x^{2} + 3 x - 1 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 3 \pm 3 ^{2} - 4 \cdot 9 ( - 1 )}{2 \cdot 9}

3^{2} - 4 \cdot 9 (- 1) = 35

x_{1, 2} = \frac{- 3 \pm 3 5}{2 \cdot 9}

Separate the solutions

x_{1} = \frac{- 3 + 3 5}{2 \cdot 9}, x_{2} = \frac{- 3 - 3 5}{2 \cdot 9}

x = \frac{- 3 + 3 5}{2 \cdot 9} : \frac{- 1 + 5}{6}

x = \frac{- 3 - 3 5}{2 \cdot 9} : - \frac{1 + 5}{6}

The solutions to the quadratic equation are:

x = \frac{- 1 + 5}{6}, x = - \frac{1 + 5}{6}

36 x^{2} - 54 x - 36 = 0

\frac{3 2}{2}

56

- 7 x + 1 \geq 22 or - 10 x + 41 \geq 81

\frac{7}{8} x \geq 6
