化简 s^2(k+(-gm-lgm-s^2m-mI-lmI)/(-g-s^2-I))

解答

化简

s^{2} (k + \frac{- g m - l g m - s ^{2} m - m I - l m I}{- g - s ^{2} - I})

\frac{s ^{2} ( - k g - k s ^{2} - k I - g m - g l m - s ^{2} m - m I - l m I )}{- g - s ^{2} - I}

求解步骤

s^{2} (k + \frac{- g m - l g m - s ^{2} m - m I - l m I}{- g - s ^{2} - I})

合并

k + \frac{- g m - l g m - s ^{2} m - m I - l m I}{- g - s ^{2} - I} : \frac{- k g - k s ^{2} - k I - g m - g l m - s ^{2} m - m I - l m I}{- g - s ^{2} - I}

= s^{2} \frac{- k g - k s ^{2} - k I - g m - g l m - s ^{2} m - m I - l m I}{- g - s ^{2} - I}

使用分式法则:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{s ^{2} ( - k g - k s ^{2} - k I - g m - g l m - s ^{2} m - m I - l m I )}{- g - s ^{2} - I}

e x p an d \frac{4}{( 4 n - 3 ) ( 4 n + 1 )}

e x p an d (1 - 3 x - 2) (x + 3 + 2)

e x p an d x (2 x - 2 x)

e x p an d 3 + x (13 + e^{14 x - 7})

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