\frac{x ^{3}}{( 3 x - 2 ) ^{2}}

\frac{x ^{3}}{9 x ^{2} - 12 x + 4}

求解步骤

\frac{x ^{3}}{( 3 x - 2 ) ^{2}}

(3 x - 2)^{2} = 9 x^{2} - 12 x + 4

= \frac{x ^{3}}{9 x ^{2} - 12 x + 4}

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

e x p an d \frac{2 ( 6 - 1 )}{5}

e x p an d d y + (y cot (g) x - e^{c o s (x)}) d x

e x p an d (a e^{x} - b e^{- x})^{2}

e x p an d - 3 x (c_{1} (2 x ln (x) + x))
