9 x^{2} - 17 x - 2 = 0

x = 2, x = - \frac{1}{9}

Decimal Notation

x = 2, x = - 0.11111 \dots

Solution steps

9 x^{2} - 17 x - 2 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 17 ) \pm ( - 17 ) ^{2} - 4 \cdot 9 ( - 2 )}{2 \cdot 9}

(- 17)^{2} - 4 \cdot 9 (- 2) = 19

x_{1, 2} = \frac{- ( - 17 ) \pm 19}{2 \cdot 9}

Separate the solutions

x_{1} = \frac{- ( - 17 ) + 19}{2 \cdot 9}, x_{2} = \frac{- ( - 17 ) - 19}{2 \cdot 9}

x = \frac{- ( - 17 ) + 19}{2 \cdot 9} : 2

x = \frac{- ( - 17 ) - 19}{2 \cdot 9} : - \frac{1}{9}

The solutions to the quadratic equation are:

x = 2, x = - \frac{1}{9}

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

\frac{1}{3} \cdot \frac{5}{6}

\frac{- 6 + - 54}{3}

x^{2} - 2 x - 8 x

- 10 ∣ n + 2 ∣ = - 70
