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

x = \frac{- 5 + 85}{6}, x = \frac{- 5 - 85}{6}

Decimal Notation

x = 0.70325 \dots, x = - 2.36992 \dots

Solution steps

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

Solve with the quadratic formula

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

5^{2} - 4 \cdot 3 (- 5) = 85

x_{1, 2} = \frac{- 5 \pm 85}{2 \cdot 3}

Separate the solutions

x_{1} = \frac{- 5 + 85}{2 \cdot 3}, x_{2} = \frac{- 5 - 85}{2 \cdot 3}

x = \frac{- 5 + 85}{2 \cdot 3} : \frac{- 5 + 85}{6}

x = \frac{- 5 - 85}{2 \cdot 3} : \frac{- 5 - 85}{6}

The solutions to the quadratic equation are:

x = \frac{- 5 + 85}{6}, x = \frac{- 5 - 85}{6}

4 - 4 x < 20 and 3 - x > 0

3 q^{2} - 9 q

- 16 < - 3 x + 8 < - 7

e^{- \frac{3}{4}}

\frac{2 x + 1}{3 x - 1} > \frac{2 x + 5}{3 x + 2}
