\frac{( - B + d - 2 \cdot c )}{( B + d + 2 \cdot a )}

\frac{- B + d - 2 c}{B + d + 2 a}

求解步骤

\frac{( - B + d - 2 c )}{( B + d + 2 a )}

(a) = a

= \frac{- B + d - 2 c}{B + d + 2 a}

e x p an d \frac{x ^{2} + 12}{( x ^{2} + 9 ) ( x ^{3} + 2 x ^{2} - x - 2 )}

e x p an d 2 u y^{2} (y d u + u d y) + (y^{2} - 3 y^{2} u^{2}) d u

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

e x p an d \frac{e ^{5 x}}{( e ^{2 x} - 1 ) ^{2}}

e x p an d 36 (e^{- 0.1 t} - 0.1 e^{- 0.1 t} t)
