expand 1/(s^2(s^2+2s+20))

expand

\frac{1}{s ^{2} ( s ^{2} + 2 s + 20 )}

\frac{1}{s ^{4} + 2 s ^{3} + 20 s ^{2}}

Solution steps

\frac{1}{s ^{2} ( s ^{2} + 2 s + 20 )}

Expand

s^{2} (s^{2} + 2 s + 20) : s^{4} + 2 s^{3} + 20 s^{2}

= \frac{1}{s ^{4} + 2 s ^{3} + 20 s ^{2}}

(x^{2} - 2 x = 15) c m^{2}

e^{2 x} (5 - e)

A (2, - 3) y B (- 5.4)

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

(- 3 x^{2} + 4 x) e^{5 x}
