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

x = - 4 + 32, x = - 4 - 32

Decimal Notation

x = 0.24264 \dots, x = - 8.24264 \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

x^{2} + 18 x + 63 = 0

3 (3 x + 2) - 6 x - 5 = 4 x^{2}

x^{2} - 116 = 0

x^{2} + 2 (4) x - 3 = (4) x^{2} + 1

6 x - 0.06 x^{2} = 0
