y (x + 1) d x - 5 d x

y x d x + y d x - 5 d x

求解步骤

y (x + 1) d x - 5 d x

乘开

y d x (x + 1) : y x d x + y d x

= y x d x + y d x - 5 d x

e x p an d \frac{9 s - 31}{( s - 3 ) ( s - 4 )}

e x p an d t (2 t, - 5, t^{2})

e x p an d \frac{x ^{2} + 3 x - 16}{( x + 7 ) ( x + 5 )}

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

e x p an d \frac{14 x - 2}{5 \cdot ( 5 + 35 x )}
