|z+2|=3

Lösung

∣ z + 2 ∣ = 3

z = - 5 or z = 1

Schritte zur Lösung

∣ z + 2 ∣ = 3

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

z + 2 = - 3 or z + 2 = 3

z + 2 = - 3 or z + 2 = 3

z = - 5 or z = 1

5 x - 4 = 2 - \frac{x}{2}

f a c t or 4 x - 16 y

f a c t or 18 v^{9} + 33 v^{8} + 14 v^{7}

x^{2} - x + 3 = 3

x^{2} - 4 x = 60
