expand (2x^2+5)/((x^2+1)^2)

expand

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

\frac{2 x ^{2} + 5}{x ^{4} + 2 x ^{2} + 1}

Solution steps

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

(x^{2} + 1)^{2} = x^{4} + 2 x^{2} + 1

= \frac{2 x ^{2} + 5}{x ^{4} + 2 x ^{2} + 1}

(s + 0.33 + 2.23 i) (s + 0.33 - 2.23 i)

\frac{224 ( 742 + 104689 )}{5945}

\frac{( x ^{5} )}{( x - 2 ) ^{2}}

\frac{10 ( s + 5 )}{s ^{2} + 3 s + 2}

\frac{9}{( x - 1 ) ( x + 2 ) ^{2}}
