expand k/(s^2(s+3)^2)

expand

\frac{k}{s ^{2} ( s + 3 ) ^{2}}

\frac{k}{s ^{4} + 6 s ^{3} + 9 s ^{2}}

Solution steps

\frac{k}{s ^{2} ( s + 3 ) ^{2}}

(s + 3)^{2} = s^{2} + 6 s + 9

= \frac{k}{s ^{2} ( s ^{2} + 6 s + 9 )}

Expand

s^{2} (s^{2} + 6 s + 9) : s^{4} + 6 s^{3} + 9 s^{2}

= \frac{k}{s ^{4} + 6 s ^{3} + 9 s ^{2}}

- 4.5 - 8.1

\frac{d}{d p} ((d (p)) (a - b p))

\frac{( a + h ) ^{2}}{h}

3 (x + Δ x)^{2} - 9 (x + Δ x)

(\frac{π}{2} + 2) 16
