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

expand

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

\frac{1}{s ^{4} + 5 s ^{2} - 4 s ^{3} - 4 s + 4}

Solution steps

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

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

= \frac{1}{( s ^{2} - 4 s + 4 ) ( s ^{2} + 1 )}

Expand

(s^{2} - 4 s + 4) (s^{2} + 1) : s^{4} + 5 s^{2} - 4 s^{3} - 4 s + 4

= \frac{1}{s ^{4} + 5 s ^{2} - 4 s ^{3} - 4 s + 4}

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

\frac{d ^{2}}{d x ^{2}} ((y) (3 x - 1)^{3})

\frac{( 4 + x ) ( x - 2 )}{x}

(1 - x + 2)^{2}

\frac{2 ^{i} ( 2 ^{k - i} - 1 ) ^{2}}{2 ^{k} - 1}
