(-2x)/((1+x^2)^2)=0

Lösung

\frac{- 2 x}{( 1 + x ^{2} ) ^{2}} = 0

x = 0

Schritte zur Lösung

\frac{- 2 x}{( 1 + x ^{2} ) ^{2}} = 0

Vereinfache

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

- \frac{2 x}{( 1 + x ^{2} ) ^{2}} = 0

\frac{f ( x )}{g ( x )} = 0 \Rightarrow f (x) = 0

2 x = 0
