|x^2-4x-4|=8

Lösung

x^{2} - 4 x - 4 = 8

x = - 2 or x = 2 or x = 6

Schritte zur Lösung

x^{2} - 4 x - 4 = 8

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x^{2} - 4 x - 4 = - 8 or x^{2} - 4 x - 4 = 8

x^{2} - 4 x - 4 = - 8 or x^{2} - 4 x - 4 = 8

x = 2 or (x = - 2 or x = 6)

x = - 2 or x = 2 or x = 6

3 x^{2} + 5 x - 2 = 0

- 10 x - 8 < x + 3

s im pl i f y 0 + \frac{π}{2}

f a c t or 3 y - 6 x + 4 x y - 2 y^{2}

2 x - \frac{1}{2} = \frac{7}{2}
