Lösung

∣ 2 x + 1 ∣ = 17

x = - 9 or x = 8

Schritte zur Lösung

∣ 2 x + 1 ∣ = 17

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

2 x + 1 = - 17 or 2 x + 1 = 17

2 x + 1 = - 17 or 2 x + 1 = 17

x = - 9 or x = 8

(7 v - 2) \frac{1}{4} + 12 = 7

\frac{x + 4}{x + 3} < \frac{x - 1}{x - 4}

4 x^{2} - 13 x + 10 = 0

3^{2} + b^{2} = 5^{2}
