expand (3s^3+2s^2+4s-1)/((s^2+4)(s^2+9))

expand

\frac{3 s ^{3} + 2 s ^{2} + 4 s - 1}{( s ^{2} + 4 ) ( s ^{2} + 9 )}

\frac{3 s ^{3} + 2 s ^{2} + 4 s - 1}{s ^{4} + 13 s ^{2} + 36}

Solution steps

\frac{3 s ^{3} + 2 s ^{2} + 4 s - 1}{( s ^{2} + 4 ) ( s ^{2} + 9 )}

Expand

(s^{2} + 4) (s^{2} + 9) : s^{4} + 13 s^{2} + 36

= \frac{3 s ^{3} + 2 s ^{2} + 4 s - 1}{s ^{4} + 13 s ^{2} + 36}

(- x cos^{2} (y) - x sin^{2} (y))^{2}

(3 - cos (t)) \cdot (sin (t))

e^{- 4 (x + h)} - (e^{- 4 x})

\frac{x + 6}{x ( x + 3 )}
