expand (s^2-4+s^3+4s)/((s^2+4)^2)

expand

\frac{s ^{2} - 4 + s ^{3} + 4 s}{( s ^{2} + 4 ) ^{2}}

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

Solution steps

\frac{s ^{2} - 4 + s ^{3} + 4 s}{( s ^{2} + 4 ) ^{2}}

(s^{2} + 4)^{2} = s^{4} + 8 s^{2} + 16

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

sin (θ) (sec (θ) - csc (θ))

e^{x} (sin (x) + cos (x))

(\frac{7 x}{3} - \frac{y}{5}) (\frac{7 x}{3} + \frac{y}{5})

(x + 6) (x - 6)

\frac{12 x ^{3} - 37 x ^{2} + 48 x - 36}{( x - 2 ) ^{2} ( x ^{2} + 4 )}
