- 9 x^{2} - 6 x - 1 = 0

x = - \frac{1}{3}

Decimal Notation

x = - 0.33333 \dots

Solution steps

- 9 x^{2} - 6 x - 1 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 6 ) \pm ( - 6 ) ^{2} - 4 ( - 9 ) ( - 1 )}{2 ( - 9 )}

(- 6)^{2} - 4 (- 9) (- 1) = 0

x_{1, 2} = \frac{- ( - 6 ) \pm 0}{2 ( - 9 )}

x = \frac{- ( - 6 )}{2 ( - 9 )}

\frac{- ( - 6 )}{2 ( - 9 )} = - \frac{1}{3}

x = - \frac{1}{3}

The solution to the quadratic equation is:

x = - \frac{1}{3}

\frac{4}{3} \cdot π

\frac{1}{5} x + \frac{1}{3} = \frac{4}{3}

(a^{\frac{1}{2}})^{2}
