\frac{6}{( s ^{2} ( 2 s + 5 ) )}

\frac{6}{2 s ^{3} + 5 s ^{2}}

求解步骤

\frac{6}{s ^{2} ( 2 s + 5 )}

乘开

s^{2} (2 s + 5) : 2 s^{3} + 5 s^{2}

= \frac{6}{2 s ^{3} + 5 s ^{2}}

e x p an d π (n^{2} - 6 n + 9)

e x p an d 6 \cdot 7^{(x + 3)^{2}}

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

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

e x p an d (8 y + 3 e) (5 y + 4 e)
