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

Lösung

erweitern

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

\frac{- 3 x ^{2} + 1}{x ^{6} + 2 x ^{4} + x ^{2}}

Schritte zur Lösung

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

(x^{3} + x)^{2} = x^{6} + 2 x^{4} + x^{2}

= \frac{- 3 x ^{2} + 1}{x ^{6} + 2 x ^{4} + x ^{2}}

\frac{d}{d x ( w )} ((w (x (w), y (w), z (w))) (x (w) y (w) + y (w) z (w) + z (w) x (w)))

e x p an d x^{8}

e x p an d \frac{19 s + 9}{( s ^{2} + 9 ) ( 2 s - 1 )}

e x p an d \frac{s ^{2} + 6}{s ( s ^{2} + 4 )}

e x p an d (- 3 a^{3} cos^{2} (x) sin (x))^{2}
