展开

\frac{( 4 x )}{( ( x - a ) ^{(2)} )}

\frac{4 x}{x ^{2} - 2 a x + a ^{2}}

求解步骤

\frac{4 x}{( x - a ) ^{2}}

(x - a)^{2} = x^{2} - 2 a x + a^{2}

= \frac{4 x}{x ^{2} - 2 a x + a ^{2}}

e x p an d \frac{- 3 x + 2}{( x - 8 ) ( 3 x + 2 )}

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

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

e x p an d \frac{h ( k - t )}{r k t}

e x p an d lo g_{3} (4 x^{12} y)
