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

expand

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

\frac{1}{s ^{3} + a s ^{2} + s + a}

Solution steps

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

Expand

(s^{2} + 1) (s + a) : s^{3} + a s^{2} + s + a

= \frac{1}{s ^{3} + a s ^{2} + s + a}

(2 x y + y^{2}) ∣ (1, 0) ∣

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

π (x)^{2} (3 x + 1) - 90 π

\frac{( 4 t ^{2} + 45 ) ^{\frac{3}{2}} - 343}{12}

\frac{( x + 2 ) ( x + 3 ) ( x + 4 )}{( x + 1 )}
