|26-4c|=30

Lösung

∣ 26 - 4 c ∣ = 30

c = - 1 or c = 14

Schritte zur Lösung

∣ 26 - 4 c ∣ = 30

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

26 - 4 c = - 30 or 26 - 4 c = 30

26 - 4 c = - 30 or 26 - 4 c = 30

c = - 1 or c = 14

∣ x + 5 ∣ - 2 = 6

∣ x - 9 ∣ + 6 = 20

∣ 4 x - 3 ∣ + 3 = 3

2 ∣ x + 9 ∣ + 3 = 55

x^{2} + 3 x - 7 = 3
