- x^{2} - 4 x - 4 = - 2

x = - 2 - 2, x = - 2 + 2

Decimal Notation

x = - 3.41421 \dots, x = - 0.58578 \dots

Solution steps

- x^{2} - 4 x - 4 = - 2

Move

2

to the left side

- x^{2} - 4 x - 2 = 0

Solve with the quadratic formula

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

(- 4)^{2} - 4 (- 1) (- 2) = 22

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

Separate the solutions

x_{1} = \frac{- ( - 4 ) + 2 2}{2 ( - 1 )}, x_{2} = \frac{- ( - 4 ) - 2 2}{2 ( - 1 )}

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

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

The solutions to the quadratic equation are:

x = - 2 - 2, x = - 2 + 2

3 x^{2} + 24 x + 50

x, f = x^{2} - 4 y

3 x^{2} + 15 x + 12 = 0

4 x^{2} - 24 x + 39 = 0

x, z = x^{2} + y^{2} - 10 x - 2 y + 36
