0.6 x^{2} + 1.4 x - 1 = 0

x = \frac{- 7 + 109}{6}, x = - \frac{7 + 109}{6}

Decimal Notation

x = 0.57338 \dots, x = - 2.90671 \dots

Solution steps

0.6 x^{2} + 1.4 x - 1 = 0

Multiply both sides by

10

6 x^{2} + 14 x - 10 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 14 \pm 1 4 ^{2} - 4 \cdot 6 ( - 10 )}{2 \cdot 6}

1 4^{2} - 4 \cdot 6 (- 10) = 2109

x_{1, 2} = \frac{- 14 \pm 2 109}{2 \cdot 6}

Separate the solutions

x_{1} = \frac{- 14 + 2 109}{2 \cdot 6}, x_{2} = \frac{- 14 - 2 109}{2 \cdot 6}

x = \frac{- 14 + 2 109}{2 \cdot 6} : \frac{- 7 + 109}{6}

x = \frac{- 14 - 2 109}{2 \cdot 6} : - \frac{7 + 109}{6}

The solutions to the quadratic equation are:

x = \frac{- 7 + 109}{6}, x = - \frac{7 + 109}{6}

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

a (x) = x^{2} + 1700 0^{-} 1

2 n^{2} + 12 n + 18 = 0

- 4 x^{2} + 2 = 0

x, 5 x^{2} + 6 x y + 5 y^{2} - 8 = 0
