expand 1+k(8/(s(s+4)(s-2)(s+2)))

expand

1 + k (\frac{8}{s ( s + 4 ) ( s - 2 ) ( s + 2 )})

1 + \frac{8 k}{s ^{4} - 4 s ^{2} + 4 s ^{3} - 16 s}

Solution steps

1 + k (\frac{8}{s ( s + 4 ) ( s - 2 ) ( s + 2 )})

Remove parentheses:

(a) = a

= 1 + k \frac{8}{s ( s + 4 ) ( s - 2 ) ( s + 2 )}

k \frac{8}{s ( s + 4 ) ( s - 2 ) ( s + 2 )} = \frac{8 k}{s ^{4} - 4 s ^{2} + 4 s ^{3} - 16 s}

= 1 + \frac{8 k}{s ^{4} + 4 s ^{3} - 4 s ^{2} - 16 s}

2 sin (\frac{π}{2} (x - 3)) + 6

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

\frac{2 x - 1}{( x - 4 ) ^{2}}

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