expand x/((xy+1)(x^2+1))

expand

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

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

Solution steps

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

Expand

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

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

(\frac{4}{( 3 - 5 ) ^{2}})^{2}

l im x \Rightarrow 5 (3 x^{2} + x - 2)

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

\frac{- 2 x - 9}{( x - 2 ) ( x - 4 ) ( x + 3 )}

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