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

- \frac{5}{4 x ^{2} - 4 x + 1}

求解步骤

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

(2 x - 1)^{2} = 4 x^{2} - 4 x + 1

= - \frac{5}{4 x ^{2} - 4 x + 1}

s im pl i f y (5 x - 1 + x + 3)^{2}

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

e x p an d (4 cos (t) - sin (t))^{2}

e x p an d sin ((2 n + 1) π)

e x p an d \frac{x ( x - 1 )}{( 15 + x ) ( 14 + x )}
