27 x^{2} + 12 x - 8 = 0

x = \frac{2 ( 7 - 1 )}{9}, x = - \frac{2 ( 1 + 7 )}{9}

Decimal Notation

x = 0.36572 \dots, x = - 0.81016 \dots

Solution steps

27 x^{2} + 12 x - 8 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 12 \pm 1 2 ^{2} - 4 \cdot 27 ( - 8 )}{2 \cdot 27}

1 2^{2} - 4 \cdot 27 (- 8) = 127

x_{1, 2} = \frac{- 12 \pm 12 7}{2 \cdot 27}

Separate the solutions

x_{1} = \frac{- 12 + 12 7}{2 \cdot 27}, x_{2} = \frac{- 12 - 12 7}{2 \cdot 27}

x = \frac{- 12 + 12 7}{2 \cdot 27} : \frac{2 ( 7 - 1 )}{9}

x = \frac{- 12 - 12 7}{2 \cdot 27} : - \frac{2 ( 1 + 7 )}{9}

The solutions to the quadratic equation are:

x = \frac{2 ( 7 - 1 )}{9}, x = - \frac{2 ( 1 + 7 )}{9}

- 3 x = - 15

14 x - 7 > 12 x

x^{4} - 11 x^{2} - 80

4 n^{2} - 1

4 > \frac{2 - 3 x}{7} \geq - 2
