解答

展开

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

\frac{2 s + 10}{s ^{3} + 2 s ^{2} + 10 s}

求解步骤

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

乘开

s (s^{2} + 2 s + 10) : s^{3} + 2 s^{2} + 10 s

= \frac{2 s + 10}{s ^{3} + 2 s ^{2} + 10 s}

e x p an d (e^{3 x} + 5)^{2}

e x p an d (1 + e^{- 2 x}) \cdot e^{x}

e x p an d \frac{1}{( x - 1 ) \cdot ( x - a )}

e x p an d 2 A - C (A = 8, - 17) (C = - 4, - 9)

e x p an d 2 (3 - e^{- 0.05 x})
