展开 (s^2+1)/(s(s+1))

解答

展开

\frac{s ^{2} + 1}{s ( s + 1 )}

\frac{s ^{2} + 1}{s ^{2} + s}

求解步骤

\frac{s ^{2} + 1}{s ( s + 1 )}

乘开

s (s + 1) : s^{2} + s

= \frac{s ^{2} + 1}{s ^{2} + s}

e x p an d 4 x^{3} + 2 x^{2} - \frac{2}{4 ^{x^{2}}}

e x p an d \frac{( k + 1 ) ( 2 k + 1 ) ( 2 k + 3 )}{3}

e x p an d 2 (e^{4} - e)

e x p an d \frac{8 x ( x ^{2} - 4 )}{( 4 x ^{4} - 32 x ^{2} + 289 ) ^{\frac{1}{2}}}

e x p an d 3 (2 x - 8 = 6)
