expand (12x)/((x^2+3)^2)

expand

\frac{12 x}{( x ^{2} + 3 ) ^{2}}

\frac{12 x}{x ^{4} + 6 x ^{2} + 9}

Solution steps

\frac{12 x}{( x ^{2} + 3 ) ^{2}}

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

= \frac{12 x}{x ^{4} + 6 x ^{2} + 9}

\frac{( x - 4 y ) ^{2}}{x ^{5} + 64 x ^{2} y ^{3}}

\frac{( x - 44 ) ( x + 5 )}{( x + 2 ) ( x - 6 )}

\frac{2 ( 2 s ^{2} + 14 s + 25 )}{( s + 4 ) ( s + 1 ) ( s + 2 )}

sin (x) cos (x) (cot (x) + sec (x))

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