expand s/((s^2+4)(s^2+1))

expand

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

\frac{s}{s ^{4} + 5 s ^{2} + 4}

Solution steps

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

Expand

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

= \frac{s}{s ^{4} + 5 s ^{2} + 4}

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

(4 x + 3 y) (x - 3 y)

(2 + \frac{x}{2})^{6}

\frac{sin ( a ) - cot ( a ) ( 1 - cos ( a ) )}{1 - cos ( a )}

R (3, - 2, - 6) y S (5, 1, - 9)
