expand (1-x)/((1+x)*(1-2x))

expand

\frac{1 - x}{( 1 + x ) \cdot ( 1 - 2 x )}

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

Solution steps

\frac{1 - x}{( 1 + x ) ( 1 - 2 x )}

Expand

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

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

(1, - 4, 1) x (2, 3, 0)

(- 17) \times (6)

\frac{( x + 4 ) ( x - 5 )}{( x - 4 ) ( x + 5 )}

\frac{8}{5}

, (x + 4) (x + 8)
