x^{2} + 13 x + 15 = 0

x = \frac{- 13 + 109}{2}, x = \frac{- 13 - 109}{2}

Decimal Notation

x = - 1.27984 \dots, x = - 11.72015 \dots

Solution steps

x^{2} + 13 x + 15 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 13 \pm 1 3 ^{2} - 4 \cdot 1 \cdot 15}{2 \cdot 1}

1 3^{2} - 4 \cdot 1 \cdot 15 = 109

x_{1, 2} = \frac{- 13 \pm 109}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 13 + 109}{2 \cdot 1}, x_{2} = \frac{- 13 - 109}{2 \cdot 1}

x = \frac{- 13 + 109}{2 \cdot 1} : \frac{- 13 + 109}{2}

x = \frac{- 13 - 109}{2 \cdot 1} : \frac{- 13 - 109}{2}

The solutions to the quadratic equation are:

x = \frac{- 13 + 109}{2}, x = \frac{- 13 - 109}{2}

x^{2} - 24 = 2 x

- 2 x^{2} - 6 = x

0 = - x^{2} + 6 x - 5

x^{2} = 91

x^{2} = 85
