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

expand

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

- e^{- x} x - e^{- x} + 1

Solution steps

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

= e^{- x} (- x - 1) + 1

Expand

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

= - e^{- x} x - e^{- x} + 1

(x^{3} + y^{3}) d x - (x y^{2}) d x

2 (- x + 2 y = - 1)

x (x cos (x) + 2 x sin (x))

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

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