x^{2} - 8 x - 2 = 0

x = 4 + 32, x = 4 - 32

Decimal Notation

x = 8.24264 \dots, x = - 0.24264 \dots

Solution steps

x^{2} - 8 x - 2 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 8 ) \pm ( - 8 ) ^{2} - 4 \cdot 1 \cdot ( - 2 )}{2 \cdot 1}

(- 8)^{2} - 4 \cdot 1 \cdot (- 2) = 62

x_{1, 2} = \frac{- ( - 8 ) \pm 6 2}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 8 ) + 6 2}{2 \cdot 1}, x_{2} = \frac{- ( - 8 ) - 6 2}{2 \cdot 1}

x = \frac{- ( - 8 ) + 6 2}{2 \cdot 1} : 4 + 32

x = \frac{- ( - 8 ) - 6 2}{2 \cdot 1} : 4 - 32

The solutions to the quadratic equation are:

x = 4 + 32, x = 4 - 32
