expand-(2x)/((x^2+c)^2)

expand

- \frac{2 x}{( x ^{2} + c ) ^{2}}

- \frac{2 x}{x ^{4} + 2 c x ^{2} + c ^{2}}

Solution steps

- \frac{2 x}{( x ^{2} + c ) ^{2}}

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

= - \frac{2 x}{x ^{4} + 2 c x ^{2} + c ^{2}}

(x - y = 5,) (x + 2 y = 7)

\frac{x}{( x - 2 ) ( x - 3 ) ( s - 6 )}

\frac{( 4 x - 1000 ) ^{2}}{9}

e^{2 x} (2 x e^{2 x} + e^{2 x})

3250 + 5160
