erweitern-(-s^2+a^2)/((s^2+a^2)^2)

Lösung

erweitern

- \frac{- s ^{2} + a ^{2}}{( s ^{2} + a ^{2} ) ^{2}}

- \frac{- s ^{2} + a ^{2}}{s ^{4} + 2 a ^{2} s ^{2} + a ^{4}}

Schritte zur Lösung

- \frac{- s ^{2} + a ^{2}}{( s ^{2} + a ^{2} ) ^{2}}

(s^{2} + a^{2})^{2} = s^{4} + 2 a^{2} s^{2} + a^{4}

= - \frac{- s ^{2} + a ^{2}}{s ^{4} + 2 a ^{2} s ^{2} + a ^{4}}
