expand (2(1+x))/(x(x^2+4))

expand

\frac{2 ( 1 + x )}{x ( x ^{2} + 4 )}

\frac{2 + 2 x}{x ^{3} + 4 x}

Solution steps

\frac{2 ( 1 + x )}{x ( x ^{2} + 4 )}

Expand

x (x^{2} + 4) : x^{3} + 4 x

= \frac{2 ( x + 1 )}{x ^{3} + 4 x}

Expand

2 (1 + x) : 2 + 2 x

= \frac{2 + 2 x}{x ^{3} + 4 x}

- 2 (- C (sin (x)) - D (cos (x)))^{2}

\frac{( 8 - x ) ^{2}}{4}

(4 x - \frac{1}{2})^{2}

(1 - x^{2}) (L ((1 - x^{2})^{\frac{m ^{2}}{2}} - m^{2} x^{2} (1 - x^{2})^{\frac{m ^{2}}{2} - 1}))

(2 - sin^{2} (x)) (cos^{2} (x))
