faktorisieren x^3-43x+42

Lösung

faktorisieren

x^{3} - 43 x + 42

(x - 1) (x - 6) (x + 7)

Schritte zur Lösung

x^{3} - 43 x + 42

Wende den rationalen Nullstellentest an

= (x - 1) \frac{x ^{3} - 43 x + 42}{x - 1}

\frac{x ^{3} - 43 x + 42}{x - 1} = x^{2} + x - 42

= (x - 1) (x^{2} + x - 42)

Faktorisiere

x^{2} + x - 42 : (x - 6) (x + 7)

= (x - 1) (x - 6) (x + 7)

- 4 < 3 x + 2 \leq 16

30 r^{2} = - 25 r

x + 5 > 2

4.6 (4.6 - x) = 6

\frac{x}{4} - 3 = 1
