expand 2e^{-t}+e^{-t}(e^t-e^z)

expand

2 e^{- t} + e^{- t} (e^{t} - e^{z})

2 e^{- t} + 1 - e^{z - t}

Solution steps

2 e^{- t} + e^{- t} (e^{t} - e^{z})

Expand

e^{- t} (e^{t} - e^{z}) : 1 - e^{z - t}

= 2 e^{- t} + 1 - e^{z - t}

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

(3 y^{3} + 4 y x + 1 + 2 x^{2} + 9 y^{2} x)

3 x + 5 + 3 x + 5

\frac{d}{d A} ([(A + B) C]^{^{'}} + B^{^{'}})

- \frac{21 x ^{2} + 2}{( 7 x ^{3} + 2 x - 4 ) ^{2}}
