|x-7|=27

Lösung

∣ x - 7 ∣ = 27

x = - 20 or x = 34

Schritte zur Lösung

∣ x - 7 ∣ = 27

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x - 7 = - 27 or x - 7 = 27

x - 7 = - 27 or x - 7 = 27

x = - 20 or x = 34

\frac{13}{3} = \frac{u}{11}

f a c t or 4 x^{2} + 16 x + 7

(x - 3)^{2} - 4 = 0
