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

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

Decimal Notation

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

Solution steps

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

Move

2

to the right side

2 x^{2} + 2 x = 2

Divide both sides by

2

\frac{2 x ^{2} + 2 x}{2} = \frac{2}{2}

x^{2} + x = 1

Rewrite in the form

(x + a)^{2} = b

(x + \frac{1}{2})^{2} = \frac{5}{4}

For

the solutions are

f (x) = a, - a

Solve

x + \frac{1}{2} = \frac{5}{4} : x = \frac{5 - 1}{2}

Solve

x + \frac{1}{2} = - \frac{5}{4} : x = \frac{- 5 - 1}{2}

The solutions to the quadratic equation are:

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

x, x^{2} + y^{2} - \frac{z ^{2}}{4} = 1

a, a^{2} + b^{2} + 1 = ab + a + b

x, 5 x^{2} - 15 x = 0

9 = (x + 1)^{2}

13.67 = (0.5 + x) \cdot (0.3 + x)
