expand 2e^{-x}x-e^{-x}(x^2-1)

expand

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

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

Solution steps

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

Expand

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

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

y^{''} (x) - 4 x y^{'} (x) + (4 x^{2} - 2) y

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

\frac{4 e ^{- 2 s}}{( s - 1 ) ( s + 4 ) ^{2}}

ln (\frac{2 x}{x - 2})

\frac{x + 2}{2 ( x - 2 ) ( x + 1 )}
