expand (x^4+3x)/((x^2-4)(x+1))

expand

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

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

Solution steps

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

Expand

(x^{2} - 4) (x + 1) : x^{3} + x^{2} - 4 x - 4

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

x (x cos (x) + 2 sin (x))

(x - x + 1) (x + 1)

(2 + y)^{12}

\frac{s ( 3 s + 5 )}{s ^{2} + s - 2}
