expand 1/((s+0.5)(s+1)^2(s+2))

expand

\frac{1}{( s + 0.5 ) ( s + 1 ) ^{2} ( s + 2 )}

\frac{1}{s ^{4} + 4.5 s ^{3} + 7 s ^{2} + 4.5 s + 1}

Solution steps

\frac{1}{( s + 0.5 ) ( s + 1 ) ^{2} ( s + 2 )}

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

= \frac{1}{( s + 0.5 ) ( s ^{2} + 2 s + 1 ) ( s + 2 )}

Expand

(s + 0.5) (s^{2} + 2 s + 1) (s + 2) : s^{4} + 4.5 s^{3} + 7 s^{2} + 4.5 s + 1

= \frac{1}{s ^{4} + 4.5 s ^{3} + 7 s ^{2} + 4.5 s + 1}

\frac{1}{( 1 + x ^{2} ) cos ( x )}

\frac{( 2 x + 6 y ) \cdot ( 3 x - 7 y )}{x y}

5 (\frac{1}{5} x - 5 = 10) 5

y \cdot e^{x 2 - x} \cdot (2 - 1)

(x^{'} - 10) (x^{2} - 1)
