|x+4|=12

Lösung

∣ x + 4 ∣ = 12

x = - 16 or x = 8

Schritte zur Lösung

∣ x + 4 ∣ = 12

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x + 4 = - 12 or x + 4 = 12

x + 4 = - 12 or x + 4 = 12

x = - 16 or x = 8

2 x \geq - 6

16 - 2 n = - 8 + 4 (n - 3)

f a c t or x^{8} - 64

8 n = n^{2}

3 x^{2} = 4 x - 15
