Lösung

erweitern

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

\frac{1 - n ^{2} x ^{2}}{1 + 2 n ^{2} x ^{2} + n ^{4} x ^{4}}

Schritte zur Lösung

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

(1 + n^{2} x^{2})^{2} = 1 + 2 n^{2} x^{2} + n^{4} x^{4}

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