-12x^2(x^3+2)=0

Lösung

- 12 x^{2} (x^{3} + 2) = 0

Lösung

x = 0, x = - 32, x = \frac{3 2}{2} + i \frac{3 2 ^{\frac{2}{3}}}{2}, x = \frac{3 2}{2} - i \frac{3 2 ^{\frac{2}{3}}}{2}

Schritte zur Lösung

- 12 x^{2} (x^{3} + 2) = 0

Faktorisiere

- 12 x^{2} (x^{3} + 2) : - 12 x^{2} (x + 32) (x^{2} - 32 x + 2^{\frac{2}{3}})

- 12 x^{2} (x + 32) (x^{2} - 32 x + 2^{\frac{2}{3}}) = 0

Anwendung des Nullfaktorprinzips: Wenn

ab = 0

dann

a = 0

oder

b = 0

x = 0 or x + 32 = 0 or x^{2} - 32 x + 2^{\frac{2}{3}} = 0

Löse

x + 32 = 0 : x = - 32

Löse

x^{2} - 32 x + 2^{\frac{2}{3}} = 0 : x = \frac{3 2}{2} + i \frac{3 2 ^{\frac{2}{3}}}{2}, x = \frac{3 2}{2} - i \frac{3 2 ^{\frac{2}{3}}}{2}

Die Lösungen sind

x = 0, x = - 32, x = \frac{3 2}{2} + i \frac{3 2 ^{\frac{2}{3}}}{2}, x = \frac{3 2}{2} - i \frac{3 2 ^{\frac{2}{3}}}{2}
