展开 (8(s+3))/((s+8)(s^2+24s+135))

解答

展开

\frac{8 ( s + 3 )}{( s + 8 ) ( s ^{2} + 24 s + 135 )}

\frac{8 s + 24}{s ^{3} + 32 s ^{2} + 327 s + 1080}

求解步骤

\frac{8 ( s + 3 )}{( s + 8 ) ( s ^{2} + 24 s + 135 )}

乘开

(s + 8) (s^{2} + 24 s + 135) : s^{3} + 32 s^{2} + 327 s + 1080

= \frac{8 ( s + 3 )}{s ^{3} + 32 s ^{2} + 327 s + 1080}

乘开

8 (s + 3) : 8 s + 24

= \frac{8 s + 24}{s ^{3} + 32 s ^{2} + 327 s + 1080}
