expand-x+(x^2+3x+2)e^{-x}

expand

- x + (x^{2} + 3 x + 2) e^{- x}

- x + e^{- x} x^{2} + 3 e^{- x} x + 2 e^{- x}

Solution steps

- x + (x^{2} + 3 x + 2) e^{- x}

= - x + e^{- x} (x^{2} + 3 x + 2)

Expand

e^{- x} (x^{2} + 3 x + 2) : e^{- x} x^{2} + 3 e^{- x} x + 2 e^{- x}

= - x + e^{- x} x^{2} + 3 e^{- x} x + 2 e^{- x}

\frac{( x + 4 ) ^{2} ( x - 5 )}{( x - 3 ) ( x + 1 ) ( x + 5 )}

4 (\frac{3}{2} - 3 y)

c (2, - 4) y (- 2, - 4) f (- 1, - 4)

\frac{( y + 8 ) ^{2}}{4}

(2 x^{3} - 8) (3 x + 6)
