- \frac{5}{( x - 1 ) ^{2}}

- \frac{5}{x ^{2} - 2 x + 1}

求解步骤

- \frac{5}{( x - 1 ) ^{2}}

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

= - \frac{5}{x ^{2} - 2 x + 1}

e x p an d (t - 3) H (t - 3)

e x p an d 3 (\frac{1}{5} x + \frac{2}{5} y)

\frac{\partial}{\partial x} ((z) ((8 x + 2 y)^{4}))

s im pl i f y (x^{3} + 89 + x^{3} + 9)^{2}

e x p an d \frac{( 2 x ^{2} + x + 8 )}{( x ^{2} + 4 ) ^{2}}
