expand-7/(s(s+2)^2)

Solution

expand

- \frac{7}{s ( s + 2 ) ^{2}}

Solution

- \frac{7}{s ^{3} + 4 s ^{2} + 4 s}

Solution steps

- \frac{7}{s ( s + 2 ) ^{2}}

(s + 2)^{2} = s^{2} + 4 s + 4

= - \frac{7}{s ( s ^{2} + 4 s + 4 )}

Expand

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

= - \frac{7}{s ^{3} + 4 s ^{2} + 4 s}

Popular Examples
