expand 3/((x^2+2)(1-x))

expand

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

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

Solution steps

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

Expand

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

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

\frac{( - 1 ) ^{k} k !}{3 ^{k} ( k + 1 )}

\frac{s - 10}{( s + 4 ) ( s ^{2} + 1 )}

(ey + 1)^{2}

(e + 1)^{3}

\frac{2 cos ( \frac{πn}{2} )}{( n + 1 ) ( - n + 1 )}
