9 x^{2} - 14 x - 8 = 0

x = 2, x = - \frac{4}{9}

Decimal Notation

x = 2, x = - 0.44444 \dots

Solution steps

9 x^{2} - 14 x - 8 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 14 ) \pm ( - 14 ) ^{2} - 4 \cdot 9 ( - 8 )}{2 \cdot 9}

(- 14)^{2} - 4 \cdot 9 (- 8) = 22

x_{1, 2} = \frac{- ( - 14 ) \pm 22}{2 \cdot 9}

Separate the solutions

x_{1} = \frac{- ( - 14 ) + 22}{2 \cdot 9}, x_{2} = \frac{- ( - 14 ) - 22}{2 \cdot 9}

x = \frac{- ( - 14 ) + 22}{2 \cdot 9} : 2

x = \frac{- ( - 14 ) - 22}{2 \cdot 9} : - \frac{4}{9}

The solutions to the quadratic equation are:

x = 2, x = - \frac{4}{9}

6 n^{2} + 9 n + 1 = 0

x^{2} + 15 x + 2 = 0

8 v^{2} - 6 = - 101

e^{2} x^{2} - 5 x - 7 = 1

x^{2} + 25 = 12 x
