Lösung

∣ x - 2 ∣ = 7

x = - 5 or x = 9

Schritte zur Lösung

∣ x - 2 ∣ = 7

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x - 2 = - 7 or x - 2 = 7

x - 2 = - 7 or x - 2 = 7

x = - 5 or x = 9

x^{2} + 14 x + 50 = 0

s im pl i f y 9^{2} + 1 2^{2}

121 x^{2} + 24 x + 2 = 0

- 4 x - 11 > 5 or 8 x - 7 > 9

2 y = 5 y^{2} - 3
