faktorisieren x^3+7x^2+2x-40

Lösung

faktorisieren

x^{3} + 7 x^{2} + 2 x - 40

Lösung

(x - 2) (x + 4) (x + 5)

Schritte zur Lösung

x^{3} + 7 x^{2} + 2 x - 40

Wende den rationalen Nullstellentest an

= (x - 2) \frac{x ^{3} + 7 x ^{2} + 2 x - 40}{x - 2}

\frac{x ^{3} + 7 x ^{2} + 2 x - 40}{x - 2} = x^{2} + 9 x + 20

= (x - 2) (x^{2} + 9 x + 20)

Faktorisiere

x^{2} + 9 x + 20 : (x + 4) (x + 5)

= (x - 2) (x + 4) (x + 5)

Beliebte Beispiele

1.2 x + 1.8 \leq 7.8

3 x^{2} + 18 x + 34 = 7

- 5 ∣ 1 - 2 x ∣ = - 60

x^2-(3(7)-4)x+77-5=0

x^{2} - (3 (7) - 4) x + 77 - 5 = 0

1-[2-(3-x)]=4x-(6+x)

1 - [2 - (3 - x)] = 4 x - (6 + x)
