解答

展开

\frac{34 ( s + 4 )}{( s ^{2} + 2 s + 2 ) ( s ^{2} + 16 s + 68 )}

\frac{34 s + 136}{s ^{4} + 18 s ^{3} + 102 s ^{2} + 168 s + 136}

求解步骤

\frac{34 ( s + 4 )}{( s ^{2} + 2 s + 2 ) ( s ^{2} + 16 s + 68 )}

乘开

(s^{2} + 2 s + 2) (s^{2} + 16 s + 68) : s^{4} + 18 s^{3} + 102 s^{2} + 168 s + 136

= \frac{34 ( s + 4 )}{s ^{4} + 18 s ^{3} + 102 s ^{2} + 168 s + 136}

乘开

34 (s + 4) : 34 s + 136

= \frac{34 s + 136}{s ^{4} + 18 s ^{3} + 102 s ^{2} + 168 s + 136}
