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

\frac{1}{4 w ^{2} - 12 w + 9}

求解步骤

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

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

= \frac{1}{4 w ^{2} - 12 w + 9}

e x p an d (6 x^{2} - 8 x^{2} v + v^{2} x^{2}) (v d x + x d v)

e x p an d (7 - 3) (25 + 4)

e x p an d sec^{2} (x + y) (1 + z)

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

e x p an d 5 cos (t) (2 sin (t) - 6 tan (t))
