解答

展开

\frac{s - 10}{s ( s - 3 ) ( s + 3 )}

\frac{s - 10}{s ^{3} - 9 s}

求解步骤

\frac{s - 10}{s ( s - 3 ) ( s + 3 )}

乘开

s (s - 3) (s + 3) : s^{3} - 9 s

= \frac{s - 10}{s ^{3} - 9 s}

e x p an d (x a - x b)^{2} + (y a - y b)^{2}

e x p an d (\frac{5 x + 3}{2 y + z})^{2}

e x p an d \frac{1 + 64 m ^{3}}{1 + 4 m}

e x p an d 6 (2 e^{x^{2}} x^{2} + e^{x^{2}})

e x p an d 1 - [G_{1} (G_{3} + G_{2})] H_{1}
