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

expand

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

2 e^{- y} - 2 e^{- y} y

Solution steps

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

Apply the distributive law:

a (b - c) = ab - a c

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

= 2 e^{- y} - 2 e^{- y} y

(\frac{1}{2 a + b = - 2 ,}) (a - 2 b = 8,)

\frac{- 2 s - 7}{30 ( s ^{2} + 4 s + 13 )}

- \frac{6}{( x + 1 ) ^{4}}

(5 cos (π t) + sin (5 π t))^{2}

sin (2) (π + x)
