vereinfachen 1+k/((s+1)(s^2+s+1.5))

Lösung

vereinfachen

1 + \frac{k}{( s + 1 ) ( s ^{2} + s + 1.5 )}

\frac{s ^{3} + 2 s ^{2} + 2.5 s + 1.5 + k}{( s + 1 ) ( s ^{2} + s + 1.5 )}

Schritte zur Lösung

1 + \frac{k}{( s + 1 ) ( s ^{2} + s + 1.5 )}

Wende Bruchregel an:

1 + \frac{b}{c} = \frac{c + b}{c}

= \frac{( s + 1 ) ( s ^{2} + s + 1.5 ) + k}{( s + 1 ) ( s ^{2} + s + 1.5 )}

Vereinfache

(s + 1) (s^{2} + s + 1.5) + k : s^{3} + 2 s^{2} + 2.5 s + 1.5 + k

= \frac{s ^{3} + 2 s ^{2} + 2.5 s + 1.5 + k}{( s + 1 ) ( s ^{2} + s + 1.5 )}
