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

expand

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

\frac{1}{s ^{4} + 6 s ^{3} + 9 s ^{2}}

Solution steps

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

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

= \frac{1}{s ^{2} ( s ^{2} + 6 s + 9 )}

Expand

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

= \frac{1}{s ^{4} + 6 s ^{3} + 9 s ^{2}}

(3 u - \frac{3}{7} v)^{2}

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

\frac{a}{b ( c - d r )}

(cot (θ) + 1) (sec (θ) - 1)
