faktorisieren x^8+2x^4-80

Lösung

faktorisieren

x^{8} + 2 x^{4} - 80

(x^{4} - 8) (x^{4} + 10)

Schritte zur Lösung

x^{8} + 2 x^{4} - 80

Angenommen

u = x^{2}

= u^{4} + 2 u^{2} - 80

Faktorisiere

u^{4} + 2 u^{2} - 80 : (u^{2} - 8) (u^{2} + 10)

= (u^{2} - 8) (u^{2} + 10)

Setze in

u = x^{2}

ein

= (x^{4} - 8) (x^{4} + 10)

f a c t or cos^{3} (x) - sin^{3} (x)

f a c t or - n^{8 x + 2 y} + m^{6 x - 4 y}

f a c t or 2 x^{2} + 2 x c - 3 b x - 3 b c

f (x) = (x)^{4}

f a c t or - (5)
