x^{2} - 18 x - 2 = 0

x = 9 + 83, x = 9 - 83

Decimal Notation

x = 18.11043 \dots, x = - 0.11043 \dots

Solution steps

x^{2} - 18 x - 2 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 18 ) \pm ( - 18 ) ^{2} - 4 \cdot 1 \cdot ( - 2 )}{2 \cdot 1}

(- 18)^{2} - 4 \cdot 1 \cdot (- 2) = 283

x_{1, 2} = \frac{- ( - 18 ) \pm 2 83}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 18 ) + 2 83}{2 \cdot 1}, x_{2} = \frac{- ( - 18 ) - 2 83}{2 \cdot 1}

x = \frac{- ( - 18 ) + 2 83}{2 \cdot 1} : 9 + 83

x = \frac{- ( - 18 ) - 2 83}{2 \cdot 1} : 9 - 83

The solutions to the quadratic equation are:

x = 9 + 83, x = 9 - 83

2 x^{2} - 12 x + 23

v, m g h = \frac{1}{2} m v^{2}

9 x - 2 = - 5 x^{2}

a x^{2} + 6 x + c = 0

- 2 x^{2} - x + 28 = 0
