espandere (10)/((s+4)(s+2)^2)

Soluzione

espandere

\frac{10}{( s + 4 ) ( s + 2 ) ^{2}}

\frac{10}{s ^{3} + 8 s ^{2} + 20 s + 16}

Fasi della soluzione

\frac{10}{( s + 4 ) ( s + 2 ) ^{2}}

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

= \frac{10}{( s + 4 ) ( s ^{2} + 4 s + 4 )}

Espandi

(s + 4) (s^{2} + 4 s + 4) : s^{3} + 8 s^{2} + 20 s + 16

= \frac{10}{s ^{3} + 8 s ^{2} + 20 s + 16}

- \frac{1}{y ( y - 1 )}

\frac{1}{2 ( 10 - 6 y )}
