解答

展开

\frac{z ( 1.1353 z + 0.5941 )}{( z - 1 ) ( z ^{2} + 0.7294 )}

\frac{1.1353 z ^{2} + 0.5941 z}{z ^{3} + 0.7294 z - z ^{2} - 0.7294}

求解步骤

\frac{z ( 1.1353 z + 0.5941 )}{( z - 1 ) ( z ^{2} + 0.7294 )}

乘开

(z - 1) (z^{2} + 0.7294) : z^{3} + 0.7294 z - z^{2} - 0.7294

= \frac{z ( 1.1353 z + 0.5941 )}{z ^{3} + 0.7294 z - z ^{2} - 0.7294}

乘开

z (1.1353 z + 0.5941) : 1.1353 z^{2} + 0.5941 z

= \frac{1.1353 z ^{2} + 0.5941 z}{z ^{3} + 0.7294 z - z ^{2} - 0.7294}
