\frac{1}{( x + 1 ) ^{2} ( x - 2 ) ^{3}}

\frac{1}{x ^{5} - 4 x ^{4} + x ^{3} + 10 x ^{2} - 4 x - 8}

Schritte zur Lösung

\frac{1}{( x + 1 ) ^{2} ( x - 2 ) ^{3}}

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

= \frac{1}{( x ^{2} + 2 x + 1 ) ( x - 2 ) ^{3}}

(x - 2)^{3} = x^{3} - 6 x^{2} + 12 x - 8

= \frac{1}{( x ^{2} + 2 x + 1 ) ( x ^{3} - 6 x ^{2} + 12 x - 8 )}
