30 x^{2} + 2 x - 4 = 0

x = \frac{1}{3}, x = - \frac{2}{5}

Decimal Notation

x = 0.33333 \dots, x = - 0.4

Solution steps

30 x^{2} + 2 x - 4 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 2 \pm 2 ^{2} - 4 \cdot 30 ( - 4 )}{2 \cdot 30}

2^{2} - 4 \cdot 30 (- 4) = 22

x_{1, 2} = \frac{- 2 \pm 22}{2 \cdot 30}

Separate the solutions

x_{1} = \frac{- 2 + 22}{2 \cdot 30}, x_{2} = \frac{- 2 - 22}{2 \cdot 30}

x = \frac{- 2 + 22}{2 \cdot 30} : \frac{1}{3}

x = \frac{- 2 - 22}{2 \cdot 30} : - \frac{2}{5}

The solutions to the quadratic equation are:

x = \frac{1}{3}, x = - \frac{2}{5}

16 t^{2} - 8 t + 1 = 0

2 x^{2} - 3 x + 1 = 15

\frac{4}{9} x^{2} - \frac{8}{3} x = 0

1062.6 = 0.68 \cdot 2.14 \cdot 100 \cdot x \cdot (9.5 - 0.4 \cdot x)

2 x^{2} + 7 x - 555 = 0
