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

\frac{x}{x ^{2} + 5 x + 6}

求解步骤

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

乘开

(x + 2) (x + 3) : x^{2} + 5 x + 6

= \frac{x}{x ^{2} + 5 x + 6}

\frac{d}{d x} ((f (x, y)) (x + x^{2} - y^{2}))

e x p an d \frac{ab}{( sc + b ) ( s d + a )}

e x p an d (\frac{ln ( 6 x + 1 )}{x + 2} + \frac{6 ln ( 3 x + 6 )}{6 x + 1}) (3 x + 6)^{l n (6 x + 1)}

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

e x p an d \frac{z ^{4} - 3 z + 6}{( z + 1 ) ^{3}}
