\frac{2 t - 5}{t ( t - 3 )}

\frac{2 t - 5}{t ^{2} - 3 t}

求解步骤

\frac{2 t - 5}{t ( t - 3 )}

乘开

t (t - 3) : t^{2} - 3 t

= \frac{2 t - 5}{t ^{2} - 3 t}

e x p an d \frac{( x - 1 ) ( x - 3 ) ( x - 4 )}{x - 2}

e x p an d (- 20 x y^{2} + 6 x) d x

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

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

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