expand e^{(-2(s))}(1/(s^2)+3/s)-s

expand

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

\frac{e ^{- 2 s}}{s ^{2}} + \frac{3 e ^{- 2 s}}{s} - s

Solution steps

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

Expand

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

= \frac{e ^{- 2 s}}{s ^{2}} + \frac{3 e ^{- 2 s}}{s} - s

(- \frac{y ^{2}}{3} - 3 x^{2} = - 3) (- \frac{1}{3})

\frac{3}{( t + 1 ) ^{5}}

- \frac{1}{4} e^{- 8 t} + \frac{3}{49} (- 7 e^{- 7 t} t - e^{- 7 t})

3.924 x + 1.596 (e^{- 2.5 x} - 1)

- x^{2} (1 + 2 ln (x))
