expand (19s+9)/((s^2+9)(2s-1))

expand

\frac{19 s + 9}{( s ^{2} + 9 ) ( 2 s - 1 )}

\frac{19 s + 9}{2 s ^{3} - s ^{2} + 18 s - 9}

Solution steps

\frac{19 s + 9}{( s ^{2} + 9 ) ( 2 s - 1 )}

Expand

(s^{2} + 9) (2 s - 1) : 2 s^{3} - s^{2} + 18 s - 9

= \frac{19 s + 9}{2 s ^{3} - s ^{2} + 18 s - 9}

\frac{s ^{2} + 6}{s ( s ^{2} + 4 )}

(- 3 a^{3} cos^{2} (x) sin (x))^{2}

- \frac{( x - y ) ^{3}}{3}

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

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