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

x = \frac{- 1 + 5}{2}, x = - \frac{1 + 5}{2}

Decimal Notation

x = 0.61803 \dots, x = - 1.61803 \dots

Solution steps

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

Solve with the quadratic formula

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

2^{2} - 4 \cdot 2 (- 2) = 25

x_{1, 2} = \frac{- 2 \pm 2 5}{2 \cdot 2}

Separate the solutions

x_{1} = \frac{- 2 + 2 5}{2 \cdot 2}, x_{2} = \frac{- 2 - 2 5}{2 \cdot 2}

x = \frac{- 2 + 2 5}{2 \cdot 2} : \frac{- 1 + 5}{2}

x = \frac{- 2 - 2 5}{2 \cdot 2} : - \frac{1 + 5}{2}

The solutions to the quadratic equation are:

x = \frac{- 1 + 5}{2}, x = - \frac{1 + 5}{2}

∣ x ∣ \leq - 2

5 x - [7 - (2 x - 1)] = 3 (x - 5) + 4 (x + 3)

- 2 y < - 8

3 - ∣ 3 - 5 x ∣ = - 2
