x^3+5x^2+7x=0

Lösung

x^{3} + 5 x^{2} + 7 x = 0

Lösung

x = 0, x = - \frac{5}{2} + i \frac{3}{2}, x = - \frac{5}{2} - i \frac{3}{2}

Schritte zur Lösung

x^{3} + 5 x^{2} + 7 x = 0

Faktorisiere

x^{3} + 5 x^{2} + 7 x : x (x^{2} + 5 x + 7)

x (x^{2} + 5 x + 7) = 0

Anwendung des Nullfaktorprinzips: Wenn

ab = 0

dann

a = 0

oder

b = 0

x = 0 or x^{2} + 5 x + 7 = 0

Löse

x^{2} + 5 x + 7 = 0 : x = - \frac{5}{2} + i \frac{3}{2}, x = - \frac{5}{2} - i \frac{3}{2}

Die Lösungen sind

x = 0, x = - \frac{5}{2} + i \frac{3}{2}, x = - \frac{5}{2} - i \frac{3}{2}
