erweitern (x^3+7x+12s)/((x+1)^3(x+2))

Lösung

erweitern

\frac{x ^{3} + 7 x + 12 s}{( x + 1 ) ^{3} ( x + 2 )}

\frac{x ^{3} + 7 x + 12 s}{x ^{4} + 5 x ^{3} + 9 x ^{2} + 7 x + 2}

Schritte zur Lösung

\frac{x ^{3} + 7 x + 12 s}{( x + 1 ) ^{3} ( x + 2 )}

(x + 1)^{3} = x^{3} + 3 x^{2} + 3 x + 1

= \frac{x ^{3} + 7 x + 12 s}{( x ^{3} + 3 x ^{2} + 3 x + 1 ) ( x + 2 )}
