9 x^{2} + 6 x = 8

x = \frac{2}{3}, x = - \frac{4}{3}

Decimal Notation

x = 0.66666 \dots, x = - 1.33333 \dots

Solution steps

9 x^{2} + 6 x = 8

Move

8

to the left side

9 x^{2} + 6 x - 8 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 6 \pm 6 ^{2} - 4 \cdot 9 ( - 8 )}{2 \cdot 9}

6^{2} - 4 \cdot 9 (- 8) = 18

x_{1, 2} = \frac{- 6 \pm 18}{2 \cdot 9}

Separate the solutions

x_{1} = \frac{- 6 + 18}{2 \cdot 9}, x_{2} = \frac{- 6 - 18}{2 \cdot 9}

x = \frac{- 6 + 18}{2 \cdot 9} : \frac{2}{3}

x = \frac{- 6 - 18}{2 \cdot 9} : - \frac{4}{3}

The solutions to the quadratic equation are:

x = \frac{2}{3}, x = - \frac{4}{3}

\frac{- 1}{2 b} \cdot \frac{6}{7 b ^{2}}

0.105 5^{\frac{1}{4}}

x^{2} - 10 x < - 24

∣ 4 - 4 x ∣ \leq 3
