解答

展开

\frac{288 ( s + 2 )}{s ( s + 4 ) ( s ^{2} + 8 s + 36 )}

\frac{288 s + 576}{s ^{4} + 12 s ^{3} + 68 s ^{2} + 144 s}

求解步骤

\frac{288 ( s + 2 )}{s ( s + 4 ) ( s ^{2} + 8 s + 36 )}

乘开

s (s + 4) (s^{2} + 8 s + 36) : s^{4} + 12 s^{3} + 68 s^{2} + 144 s

= \frac{288 ( s + 2 )}{s ^{4} + 12 s ^{3} + 68 s ^{2} + 144 s}

乘开

288 (s + 2) : 288 s + 576

= \frac{288 s + 576}{s ^{4} + 12 s ^{3} + 68 s ^{2} + 144 s}
