expand x/((x^2+w^2)(x^2+4))

expand

\frac{x}{( x ^{2} + w ^{2} ) ( x ^{2} + 4 )}

\frac{x}{x ^{4} + 4 x ^{2} + x ^{2} w ^{2} + 4 w ^{2}}

Solution steps

\frac{x}{( x ^{2} + w ^{2} ) ( x ^{2} + 4 )}

Expand

(x^{2} + w^{2}) (x^{2} + 4) : x^{4} + 4 x^{2} + x^{2} w^{2} + 4 w^{2}

= \frac{x}{x ^{4} + 4 x ^{2} + x ^{2} w ^{2} + 4 w ^{2}}

- \frac{x ^{2} ( 2 x - 9 )}{6}

(cos (x) + cos (y))^{2}

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

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

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