\frac{2 ( - x + 3 )}{- 3 x + 5}

\frac{- 2 x + 6}{- 3 x + 5}

求解步骤

\frac{2 ( - x + 3 )}{- 3 x + 5}

乘开

2 (- x + 3) : - 2 x + 6

= \frac{- 2 x + 6}{- 3 x + 5}

e x p an d (x + 3) ln (x + 3)

e x p an d (x + 2.5) + 0.75

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

e x p an d \frac{6 x + 3}{x ^{2} ( x ^{2} - 4 )}

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