5 x^{2} - 6 x - 2 = - 9 x

x = \frac{2}{5}, x = - 1

Decimal Notation

x = 0.4, x = - 1

Solution steps

5 x^{2} - 6 x - 2 = - 9 x

Move

9 x

to the left side

5 x^{2} + 3 x - 2 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 3 \pm 3 ^{2} - 4 \cdot 5 ( - 2 )}{2 \cdot 5}

3^{2} - 4 \cdot 5 (- 2) = 7

x_{1, 2} = \frac{- 3 \pm 7}{2 \cdot 5}

Separate the solutions

x_{1} = \frac{- 3 + 7}{2 \cdot 5}, x_{2} = \frac{- 3 - 7}{2 \cdot 5}

x = \frac{- 3 + 7}{2 \cdot 5} : \frac{2}{5}

x = \frac{- 3 - 7}{2 \cdot 5} : - 1

The solutions to the quadratic equation are:

x = \frac{2}{5}, x = - 1

2 k^{2} - 16 k + 168 = 0

2 x (4 - 7 x) = - 9

x^{2} + 8 x + 17

0 = 30 + 3 t - \frac{9.8 t ^{2}}{2}

r^{2} - r + 49 = 0
