erweitern ((2-x^2)^2)/(2e^{5x)}

Lösung

erweitern

\frac{( 2 - x ^{2} ) ^{2}}{2 e ^{5 x}}

\frac{2}{e ^{5 x}} - \frac{2 x ^{2}}{e ^{5 x}} + \frac{x ^{4}}{2 e ^{5 x}}

Schritte zur Lösung

\frac{( 2 - x ^{2} ) ^{2}}{2 e ^{5 x}}

(2 - x^{2})^{2} = 4 - 4 x^{2} + x^{4}

= \frac{4 - 4 x ^{2} + x ^{4}}{2 e ^{5 x}}

Wende Bruchregel an:

\frac{a \pm b}{c} = \frac{a}{c} \pm \frac{b}{c}

\frac{4 - 4 x ^{2} + x ^{4}}{2 e ^{5 x}} = \frac{4}{2 e ^{5 x}} - \frac{4 x ^{2}}{2 e ^{5 x}} + \frac{x ^{4}}{2 e ^{5 x}}

= \frac{4}{2 e ^{5 x}} - \frac{4 x ^{2}}{2 e ^{5 x}} + \frac{x ^{4}}{2 e ^{5 x}}
