faktorisieren x^3-10x^2+31x-28

Lösung

faktorisieren

x^{3} - 10 x^{2} + 31 x - 28

Lösung

(x - 4) (x^{2} - 6 x + 7)

Schritte zur Lösung

x^{3} - 10 x^{2} + 31 x - 28

Wende den rationalen Nullstellentest an

= (x - 4) \frac{x ^{3} - 10 x ^{2} + 31 x - 28}{x - 4}

\frac{x ^{3} - 10 x ^{2} + 31 x - 28}{x - 4} = x^{2} - 6 x + 7

= (x - 4) (x^{2} - 6 x + 7)

7 x^{2} - 7 x + 2 = 0

0 = x^{2} + 6 x + 9

2(1/2 x-1/4)= 1/2 (3x-7)

2 (\frac{1}{2} x - \frac{1}{4}) = \frac{1}{2} (3 x - 7)
