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

x = \frac{- 15 + 173}{2}, x = \frac{- 15 - 173}{2}

Decimal Notation

x = - 0.92352 \dots, x = - 14.07647 \dots

Solution steps

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

Solve with the quadratic formula

x_{1, 2} = \frac{- 15 \pm 1 5 ^{2} - 4 \cdot 1 \cdot 13}{2 \cdot 1}

1 5^{2} - 4 \cdot 1 \cdot 13 = 173

x_{1, 2} = \frac{- 15 \pm 173}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 15 + 173}{2 \cdot 1}, x_{2} = \frac{- 15 - 173}{2 \cdot 1}

x = \frac{- 15 + 173}{2 \cdot 1} : \frac{- 15 + 173}{2}

x = \frac{- 15 - 173}{2 \cdot 1} : \frac{- 15 - 173}{2}

The solutions to the quadratic equation are:

x = \frac{- 15 + 173}{2}, x = \frac{- 15 - 173}{2}

\frac{\frac{2}{x + h} - \frac{2}{x}}{h}

6 - 3 x = x - 6

81 x^{2} = 25

2 x^{5} - 9 x^{4} + 12 x^{3} - 4 x^{2} - 8 x + 4

3 x^{2} + 5 x - 9 = 0
