展开

\frac{1 - s ( 1 - p )}{1 - s ( 1 - x )}

\frac{1 - s + s p}{1 - s + s x}

求解步骤

\frac{1 - s ( 1 - p )}{1 - s ( 1 - x )}

乘开

1 - s (1 - x) : 1 - s + s x

= \frac{1 - s ( - p + 1 )}{1 - s + s x}

乘开

1 - s (1 - p) : 1 - s + s p

= \frac{1 - s + s p}{1 - s + s x}

e x p an d \frac{( 3 c + 4 ) ( 3 c - 2 )}{144}

e x p an d (ln (x) + 1) \cdot (2 ln (x) - 1)

e x p an d (d x - 4) 3

e x p an d (- 6, - 10) y (- 2, - 2)

e x p an d 3 (x - 1 = 2 x + 9)
