expand 1/((x+1)*(x^3-1))

expand

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

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

Solution steps

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

Expand

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

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

x (54 - 4 ln (x))

\frac{50 ( s - 2 )}{s ( s ^{2} + s + 100 )}

\frac{5}{s ( s ^{2} + 10 s + 8 )}

\frac{s + 1}{s ( s ^{2} + s + 1 )}
