8 x^{2} + 2 x - 1 = 0

x = \frac{1}{4}, x = - \frac{1}{2}

Decimal Notation

x = 0.25, x = - 0.5

Solution steps

8 x^{2} + 2 x - 1 = 0

Solve with the quadratic formula

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

2^{2} - 4 \cdot 8 (- 1) = 6

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

Separate the solutions

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

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

x = \frac{- 2 - 6}{2 \cdot 8} : - \frac{1}{2}

The solutions to the quadratic equation are:

x = \frac{1}{4}, x = - \frac{1}{2}

x, 2 x^{2} + y^{2} - 4 x + 2 y + 3 = 0

3 x^{2} + 11 x = 4

25 (x^{2} - 5) - 17 = 2

y, x = y^{2}

x^{2} - 8 x - 25 = 0
