expand 40(e^{-2x}-2e^{-2x}x)

expand

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

40 e^{- 2 x} - 80 e^{- 2 x} x

Solution steps

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

Apply the distributive law:

a (b - c) = ab - a c

a = 40, b = e^{- 2 x}, c = 2 e^{- 2 x} x

= 40 e^{- 2 x} - 40 \cdot 2 e^{- 2 x} x

Multiply the numbers:

40 \cdot 2 = 80

= 40 e^{- 2 x} - 80 e^{- 2 x} x

(3 arctan (x) - π) (x^{2} - 3)

\frac{( n + 1 ) ( n + 2 ) ( n + 3 ) ( n + 4 )}{4}

\frac{125 ( 2 n + 1 ) ( n + 1 )}{6}

\frac{( 3 )}{( ( x + 1 ) ( x + 2 ) )}

lo g_{3} (x - 2)
