expand (10)/((s+2)(s+1)^3)

expand

\frac{10}{( s + 2 ) ( s + 1 ) ^{3}}

\frac{10}{s ^{4} + 5 s ^{3} + 9 s ^{2} + 7 s + 2}

Solution steps

\frac{10}{( s + 2 ) ( s + 1 ) ^{3}}

(s + 1)^{3} = s^{3} + 3 s^{2} + 3 s + 1

= \frac{10}{( s + 2 ) ( s ^{3} + 3 s ^{2} + 3 s + 1 )}

Expand

(s + 2) (s^{3} + 3 s^{2} + 3 s + 1) : s^{4} + 5 s^{3} + 9 s^{2} + 7 s + 2

= \frac{10}{s ^{4} + 5 s ^{3} + 9 s ^{2} + 7 s + 2}

5 (10 + 2)

8 \cdot (\frac{x}{2} + \frac{1}{4})

(y^{2} + x y^{3}) d x + (5 y^{2} - x y + y^{3} sin (y)) d y

(x + sin (x))^{2}
