\frac{9 x - 8}{( x - 3 ) ( 2 x - 5 )}

\frac{9 x - 8}{2 x ^{2} - 11 x + 15}

求解步骤

\frac{9 x - 8}{( x - 3 ) ( 2 x - 5 )}

乘开

(x - 3) (2 x - 5) : 2 x^{2} - 11 x + 15

= \frac{9 x - 8}{2 x ^{2} - 11 x + 15}

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

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

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

e x p an d 5 y^{3} d x - y^{2} (- 2 x + y^{2} z^{4}) d y

e x p an d (e^{3 t} + 5)^{2}
