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

x = \frac{- 1 + 15}{7}, x = - \frac{1 + 15}{7}

Decimal Notation

x = 0.41042 \dots, x = - 0.69614 \dots

Solution steps

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

Solve with the quadratic formula

x_{1, 2} = \frac{- 2 \pm 2 ^{2} - 4 \cdot 7 ( - 2 )}{2 \cdot 7}

2^{2} - 4 \cdot 7 (- 2) = 215

x_{1, 2} = \frac{- 2 \pm 2 15}{2 \cdot 7}

Separate the solutions

x_{1} = \frac{- 2 + 2 15}{2 \cdot 7}, x_{2} = \frac{- 2 - 2 15}{2 \cdot 7}

x = \frac{- 2 + 2 15}{2 \cdot 7} : \frac{- 1 + 15}{7}

x = \frac{- 2 - 2 15}{2 \cdot 7} : - \frac{1 + 15}{7}

The solutions to the quadratic equation are:

x = \frac{- 1 + 15}{7}, x = - \frac{1 + 15}{7}

3 X^{2} - 1 = 0

y, f = 13 - x^{3} - y^{2} - z^{2} - 12 x y - 2 z

4 x^{2} = 5 x - 6

y, y^{2} - 4 x - 6 y + 1 = 0

(3 x + 3) (x - 1) = x (x + 1)
