|4x-12|=16

Lösung

∣ 4 x - 12 ∣ = 16

x = - 1 or x = 7

Schritte zur Lösung

∣ 4 x - 12 ∣ = 16

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

4 x - 12 = - 16 or 4 x - 12 = 16

4 x - 12 = - 16 or 4 x - 12 = 16

x = - 1 or x = 7

2 a^{2} - a + [2 (a - 1) (a + 3)] = 26

1^{2} + 1^{2}

15 v^{2} - 8 v + 3 = 6 v

7 (x + 2) = 6 (x + 5)
