4 x^{2} + 20 x + 13 = 0

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

Solution steps

4 x^{2} + 20 x + 13 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 20 \pm 2 0 ^{2} - 4 \cdot 4 \cdot 13}{2 \cdot 4}

2 0^{2} - 4 \cdot 4 \cdot 13 = 83

x_{1, 2} = \frac{- 20 \pm 8 3}{2 \cdot 4}

Separate the solutions

x_{1} = \frac{- 20 + 8 3}{2 \cdot 4}, x_{2} = \frac{- 20 - 8 3}{2 \cdot 4}

x = \frac{- 20 + 8 3}{2 \cdot 4} : \frac{- 5 + 2 3}{2}

x = \frac{- 20 - 8 3}{2 \cdot 4} : - \frac{5 + 2 3}{2}

The solutions to the quadratic equation are:

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

6 - x > 0

- 12 - 4

3 (\frac{2}{3})^{2}

2 x^{2} - 3 x + 15 = 0

\frac{1 0 ^{- 9}}{2}
