expand (x^2+5x-1)/((x^2+3)^2)

expand

\frac{x ^{2} + 5 x - 1}{( x ^{2} + 3 ) ^{2}}

\frac{x ^{2} + 5 x - 1}{x ^{4} + 6 x ^{2} + 9}

Solution steps

\frac{x ^{2} + 5 x - 1}{( x ^{2} + 3 ) ^{2}}

(x^{2} + 3)^{2} = x^{4} + 6 x^{2} + 9

= \frac{x ^{2} + 5 x - 1}{x ^{4} + 6 x ^{2} + 9}

(x^{2} y^{2} + 1) d x + (2 x^{2}) d y

\frac{( - 3 s ^{2} - 16 s + 12 )}{( s ^{2} + 4 ) ( s + 1 ) ( s - 4 )}
