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

expand

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

2 e^{- x} - 2 e^{- x} x

Solution steps

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

Apply the distributive law:

a (b - c) = ab - a c

a = 2, b = e^{- x}, c = e^{- x} x

= 2 e^{- x} - 2 e^{- x} x

\frac{x}{( 1 - x ) ^{3}}

(y^{2} - 2 x y + 6 x) d x - (x^{2} - 2 x y + 2) d y

\frac{\frac{d}{d x} ( 3 )}{2 ( 2 x ^{4} + 5 x ^{2} + 3 ) ^{4}}

5 \cdot \frac{1}{4} + (0.01 - 3) \cdot \frac{1}{4} + (- 3 \cdot \frac{1}{400})
