expand x/((s^2+x^2)(s^2+4s+13))

expand

\frac{x}{( s ^{2} + x ^{2} ) ( s ^{2} + 4 s + 13 )}

\frac{x}{s ^{4} + 4 s ^{3} + 13 s ^{2} + x ^{2} s ^{2} + 4 x ^{2} s + 13 x ^{2}}

Solution steps

\frac{x}{( s ^{2} + x ^{2} ) ( s ^{2} + 4 s + 13 )}

Expand

(s^{2} + x^{2}) (s^{2} + 4 s + 13) : s^{4} + 4 s^{3} + 13 s^{2} + x^{2} s^{2} + 4 x^{2} s + 13 x^{2}

= \frac{x}{s ^{4} + 4 s ^{3} + 13 s ^{2} + x ^{2} s ^{2} + 4 x ^{2} s + 13 x ^{2}}

\frac{k ( s + 0.5 )}{( s + 1 ) ( s ^{2} + 2 s ) + k ( s + 0.5 )}

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

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

\frac{( x - 5 )}{( 1 - x ) ( x + 2 )}

\frac{( 7 x - 1 ) ( 5 x - 2 )}{( x - 2 )}
