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

expand

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

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

Solution steps

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

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

= \frac{x ^{2} + x}{1 - 3 x + 3 x ^{2} - x ^{3}}

\frac{2 cos ( z )}{( z - 3 ) ^{3}}

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

(sinh (x) + cosh (x))^{4}

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

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