x^{2} + 15 x - 800 = 0

x = \frac{- 15 + 5 137}{2}, x = \frac{- 15 - 5 137}{2}

Decimal Notation

x = 21.76174 \dots, x = - 36.76174 \dots

Solution steps

x^{2} + 15 x - 800 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 15 \pm 1 5 ^{2} - 4 \cdot 1 \cdot ( - 800 )}{2 \cdot 1}

1 5^{2} - 4 \cdot 1 \cdot (- 800) = 5137

x_{1, 2} = \frac{- 15 \pm 5 137}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 15 + 5 137}{2 \cdot 1}, x_{2} = \frac{- 15 - 5 137}{2 \cdot 1}

x = \frac{- 15 + 5 137}{2 \cdot 1} : \frac{- 15 + 5 137}{2}

x = \frac{- 15 - 5 137}{2 \cdot 1} : \frac{- 15 - 5 137}{2}

The solutions to the quadratic equation are:

x = \frac{- 15 + 5 137}{2}, x = \frac{- 15 - 5 137}{2}

2 a^{2} - a - 11 = - 3

x^{2} - 16 x = - 73

25 x^{2} - 16 = 0

2 z^{2} + 5.5 z + 3.75 = 0

10 x^{2} - 7 x - 1 = 0
