\frac{( x - 3 )}{( x - 1 ) ^{2}}

\frac{x - 3}{x ^{2} - 2 x + 1}

求解步骤

\frac{x - 3}{( x - 1 ) ^{2}}

(x - 1)^{2} = x^{2} - 2 x + 1

= \frac{x - 3}{x ^{2} - 2 x + 1}

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

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

e x p an d \frac{18 x ^{3}}{( z - 0.5 ) ( z - 0.8 ) ^{2}}

e x p an d x (x - \frac{π}{2})

e x p an d (k + 1) \cdot (k + 1)!
