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

Solution

simplify

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

Solution

\frac{2 e ^{- x} - 1}{e ^{x}}

Solution steps

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

Apply exponent rule:

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

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

Multiply fractions:

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

= \frac{1 \cdot ( 2 e ^{- x} - 1 )}{e ^{x}}

1 \cdot (2 e^{- x} - 1) = 2 e^{- x} - 1

= \frac{2 e ^{- x} - 1}{e ^{x}}
