expand 2/((1-y)(2-x-y))

expand

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

\frac{2}{2 - x - 3 y + y x + y ^{2}}

Solution steps

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

Expand

(1 - y) (2 - x - y) : 2 - x - 3 y + y x + y^{2}

= \frac{2}{2 - x - 3 y + y x + y ^{2}}

ln (x^{2} + 1) + x^{2} (2 x arctan (x) - 1) 6

\frac{( x ^{4} + x )}{x}

\frac{( s + 3 ) ( s + 2 )}{( s + 1 ) ( s ^{2} + 2 s + 3 )}

\frac{( x ^{2} + 4 ) ^{2}}{( 2 x ^{3} - 1 ) ^{3}}

4 x^{4 x^{2}} (2 x ln (x) + x)
