|x^2+7x+14|=4

Lösung

x^{2} + 7 x + 14 = 4

x = - 5 or x = - 2

Schritte zur Lösung

x^{2} + 7 x + 14 = 4

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x^{2} + 7 x + 14 = - 4 or x^{2} + 7 x + 14 = 4

x^{2} + 7 x + 14 = - 4 or x^{2} + 7 x + 14 = 4

keine L \overset{o}{¨} sung or (x = - 5 or x = - 2)

x = - 5 or x = - 2

- 2 ∣ 7 - 3 x ∣ - 6 = - 14

∣ 10 x - 5 ∣ = - 65

so l v e f or y, ∣ x - y ∣ = ∣ y - x ∣

∣ 12 x + 1 ∣ - 13 = - 1

∣ 2 + 3 x ∣ = ∣ 4 - 2 x ∣
