expand A(e^{-x}-e^{-x}x)

expand

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

A e^{- x} - A e^{- x} x

Solution steps

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

Apply the distributive law:

a (b - c) = ab - a c

a = A, b = e^{- x}, c = e^{- x} x

= A e^{- x} - A e^{- x} x

(- 1, 2) y (- 3, - 6)

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

(x + 5 + 2)^{2}

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