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

expand

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

\frac{4 - x}{x ^{3} + x + x ^{2} + 1}

Solution steps

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

Expand

(x + 1) (x^{2} + 1) : x^{3} + x + x^{2} + 1

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

2 (- 1 + 3) (1 + 2)

- t^{2} (\frac{12 t}{625} - \frac{12}{125})

- x (\frac{12 t ^{12} ln ( t ) - t ^{12}}{1152 x ^{9}} + C)

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

(3 + \frac{x}{2})^{5}
