∣ 3 x ∣ = 12

x = - 4 or x = 4

Schritte zur Lösung

∣ 3 x ∣ = 12

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

3 x = - 12 or 3 x = 12

3 x = - 12 or 3 x = 12

x = - 4 or x = 4

f a c t or x^{3} - 13 x - 12

s im pl i f y (\frac{x}{3})^{3}

f a c t or 2 x^{3} - 5 x^{2} - 28 x + 15

3 x - 5 = 7 x - 17

\frac{5}{6} = \frac{x}{24}
