erweitern (5s^2-2s-19)/((s-1)^2(s+3))

Lösung

erweitern

\frac{5 s ^{2} - 2 s - 19}{( s - 1 ) ^{2} ( s + 3 )}

\frac{5 s ^{2} - 2 s - 19}{s ^{3} + s ^{2} - 5 s + 3}

Schritte zur Lösung

\frac{5 s ^{2} - 2 s - 19}{( s - 1 ) ^{2} ( s + 3 )}

(s - 1)^{2} = s^{2} - 2 s + 1

= \frac{5 s ^{2} - 2 s - 19}{( s ^{2} - 2 s + 1 ) ( s + 3 )}
