x^3+5x-774=0

Lösung

x^{3} + 5 x - 774 = 0

Lösung

x = 9, x = - \frac{9}{2} + i \frac{263}{2}, x = - \frac{9}{2} - i \frac{263}{2}

Schritte zur Lösung

x^{3} + 5 x - 774 = 0

Faktorisiere

x^{3} + 5 x - 774 : (x - 9) (x^{2} + 9 x + 86)

(x - 9) (x^{2} + 9 x + 86) = 0

Anwendung des Nullfaktorprinzips: Wenn

ab = 0

dann

a = 0

oder

b = 0

x - 9 = 0 or x^{2} + 9 x + 86 = 0

Löse

x - 9 = 0 : x = 9

Löse

x^{2} + 9 x + 86 = 0 : x = - \frac{9}{2} + i \frac{263}{2}, x = - \frac{9}{2} - i \frac{263}{2}

Die Lösungen sind

x = 9, x = - \frac{9}{2} + i \frac{263}{2}, x = - \frac{9}{2} - i \frac{263}{2}
