|x-9|=9

Lösung

∣ x - 9 ∣ = 9

x = 0 or x = 18

Schritte zur Lösung

∣ x - 9 ∣ = 9

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x - 9 = - 9 or x - 9 = 9

x - 9 = - 9 or x - 9 = 9

x = 0 or x = 18

x^{2} + 11 x + 28 \leq 0

2 x + 42 + x - 7 + x - 7 = 180

2 x^{2} + 5 x = 3

f a c t or x^{3} - 8 x^{2} + 5 x + 14
