expand (10x)/((x^2+1)^2)

expand

\frac{10 x}{( x ^{2} + 1 ) ^{2}}

\frac{10 x}{x ^{4} + 2 x ^{2} + 1}

Solution steps

\frac{10 x}{( x ^{2} + 1 ) ^{2}}

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

= \frac{10 x}{x ^{4} + 2 x ^{2} + 1}

\frac{1}{4} (3 (1, 2, 3, - 2) + 2 (0, - 2, 1, 2) - (2, - 2, 1, 3))

\frac{2 n + 3}{( n - 1 ) n ( n + 1 )}

x \cdot y \cdot (4 - x^{2} - \frac{y ^{2}}{4})

sinh (3 (t - 5))
