faktorisieren x^3+13x^2+32x+20

Lösung

faktorisieren

x^{3} + 13 x^{2} + 32 x + 20

(x + 1) (x + 2) (x + 10)

Schritte zur Lösung

x^{3} + 13 x^{2} + 32 x + 20

Wende den rationalen Nullstellentest an

= (x + 1) \frac{x ^{3} + 13 x ^{2} + 32 x + 20}{x + 1}

\frac{x ^{3} + 13 x ^{2} + 32 x + 20}{x + 1} = x^{2} + 12 x + 20

= (x + 1) (x^{2} + 12 x + 20)

Faktorisiere

x^{2} + 12 x + 20 : (x + 2) (x + 10)

= (x + 1) (x + 2) (x + 10)
