erweitern (12x(-2x^3+1))/((x^3+1)^3)

Lösung

erweitern

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

\frac{- 24 x ^{4} + 12 x}{x ^{9} + 3 x ^{6} + 3 x ^{3} + 1}

Schritte zur Lösung

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

(x^{3} + 1)^{3} = x^{9} + 3 x^{6} + 3 x^{3} + 1

= \frac{12 x ( - 2 x ^{3} + 1 )}{x ^{9} + 3 x ^{6} + 3 x ^{3} + 1}
