expand 1/((s+7)(s^2+6s+3))

expand

\frac{1}{( s + 7 ) ( s ^{2} + 6 s + 3 )}

\frac{1}{s ^{3} + 13 s ^{2} + 45 s + 21}

Solution steps

\frac{1}{( s + 7 ) ( s ^{2} + 6 s + 3 )}

Expand

(s + 7) (s^{2} + 6 s + 3) : s^{3} + 13 s^{2} + 45 s + 21

= \frac{1}{s ^{3} + 13 s ^{2} + 45 s + 21}

\frac{d}{d t} ((x) (- B y (x, t, B) + t))

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

(e^{2 x} - 1) (e^{2 y} + 1)

ro t (2 x y, x^{2} + z^{2}, 2 yz)

\frac{x}{y ( x y + y ) ( x - 1 )}
