|m+7|=12

Lösung

∣ m + 7 ∣ = 12

m = - 19 or m = 5

Schritte zur Lösung

∣ m + 7 ∣ = 12

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

m + 7 = - 12 or m + 7 = 12

m + 7 = - 12 or m + 7 = 12

m = - 19 or m = 5

- 3 x^{2} = 150

f a c t or x^{3} - 8 x^{2} + x + 42

∣ x - 3 ∣ = ∣ 3 x + 5 ∣

2 x^{2} = 2 x + 3

2 - (z - 2)^{2} = z^{2}
