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

Solution

simplify

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

Solution

\frac{- x - 1}{e ^{x}}

Solution steps

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

Apply exponent rule:

a^{- b} = \frac{1}{a ^{b}}

= \frac{1}{e ^{x}} (- x - 1)

Multiply fractions:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{1 \cdot ( - x - 1 )}{e ^{x}}

1 \cdot (- x - 1) = - x - 1

= \frac{- x - 1}{e ^{x}}
