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

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

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}

x - 1 + 2 x - 1 = - 5

2 w^{2} + 3 w - 77

2 x = 9 - x^{2}
