z = - 8 or z = 8

Schritte zur Lösung

∣ 5 z ∣ = 40

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

5 z = - 40 or 5 z = 40

5 z = - 40 or 5 z = 40

z = - 8 or z = 8

f a c t or 3 c^{2} + 2 c - 16

3 x + 6 = 9 x - 12

(x - 2) (x - 1) = (x - 2) (x - 1)

3 x^{2} = 21 x

8 y - 9 y = 4
