3x^6-x^4-12x^2+4=0

Lösung

3 x^{6} - x^{4} - 12 x^{2} + 4 = 0

Lösung

x = \frac{1}{3}, x = - \frac{1}{3}, x = 2 i, x = - 2 i, x = 2, x = - 2

Schritte zur Lösung

3 x^{6} - x^{4} - 12 x^{2} + 4 = 0

Schreibe die Gleichung um mit

u = x^{2}, u^{2} = x^{4}

und

u^{3} = x^{6}

3 u^{3} - u^{2} - 12 u + 4 = 0

Löse

3 u^{3} - u^{2} - 12 u + 4 = 0 : u = \frac{1}{3}, u = - 2, u = 2

u = \frac{1}{3}, u = - 2, u = 2

Setze

u = x^{2} w i e d er e in,
