erweitern (5(3-x^2))/((x^2+3)^2)

Lösung

erweitern

\frac{5 ( 3 - x ^{2} )}{( x ^{2} + 3 ) ^{2}}

\frac{15 - 5 x ^{2}}{x ^{4} + 6 x ^{2} + 9}

Schritte zur Lösung

\frac{5 ( 3 - x ^{2} )}{( x ^{2} + 3 ) ^{2}}

(x^{2} + 3)^{2} = x^{4} + 6 x^{2} + 9

= \frac{5 ( - x ^{2} + 3 )}{x ^{4} + 6 x ^{2} + 9}
