What is expand (s^3+sx^2+s+5)/((s^2+1)(s^2+4s+8)) ?

The solution to expand (s^3+sx^2+s+5)/((s^2+1)(s^2+4s+8)) is (s^3+sx^2+s+5)/(s^4+4s^3+9s^2+4s+8)

expand (s^3+sx^2+s+5)/((s^2+1)(s^2+4s+8))

expand

\frac{s ^{3} + s x ^{2} + s + 5}{( s ^{2} + 1 ) ( s ^{2} + 4 s + 8 )}

\frac{s ^{3} + s x ^{2} + s + 5}{s ^{4} + 4 s ^{3} + 9 s ^{2} + 4 s + 8}

Solution steps

\frac{s ^{3} + s x ^{2} + s + 5}{( s ^{2} + 1 ) ( s ^{2} + 4 s + 8 )}

Expand

(s^{2} + 1) (s^{2} + 4 s + 8) : s^{4} + 4 s^{3} + 9 s^{2} + 4 s + 8

= \frac{s ^{3} + s x ^{2} + s + 5}{s ^{4} + 4 s ^{3} + 9 s ^{2} + 4 s + 8}

1 + cos (\frac{1}{2} (π - x))

\frac{6 x ^{2} - 4 x y - 2 y ^{2} - 19 x - y + 10}{( 6 x + 2 y ) ( x - y )}

\frac{- 1 + ( - \frac{1}{3} )}{2}

- \frac{3 ( 5 - 1 )}{4}

\frac{x ^{2} - 36 x}{( x + 6 ) ( x ^{2} - 7 x + 6 )}
