expand 4(e^{-2x}-2e^{-2x}x)

expand

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

4 e^{- 2 x} - 8 e^{- 2 x} x

Solution steps

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

Apply the distributive law:

a (b - c) = ab - a c

a = 4, b = e^{- 2 x}, c = 2 e^{- 2 x} x

= 4 e^{- 2 x} - 4 \cdot 2 e^{- 2 x} x

Multiply the numbers:

4 \cdot 2 = 8

= 4 e^{- 2 x} - 8 e^{- 2 x} x

\frac{1}{2 h ( b + a )}

\frac{( 12 y + 3 x ) ( 28 y + 3 x )}{16}

\frac{1}{( s + 1 ) ( s ^{2} + 2 s + 2 )}

x (y^{2} + y + Δ (y^{2} + y))

\frac{1}{( s ) ( s + 1 ) ( s ^{2} + 2 )}
