x = - 2 or x = 3

Schritte zur Lösung

∣ 3 - 6 x ∣ = 15

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

3 - 6 x = - 15 or 3 - 6 x = 15

3 - 6 x = - 15 or 3 - 6 x = 15

x = - 2 or x = 3

- 4 q + 64 = 0

7 - 3 ∣ 3 - 2 x ∣ = - 29

s im pl i f y \frac{\frac{5}{2 x + 2 h + 3} - \frac{5}{2 x + 3}}{h}

∣ m ∣ - 2 > 0

∣ x - 2 ∣ \leq \frac{1}{5} ∣ 2 x - 3 ∣
