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

expand

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

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

Solution steps

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

Apply the distributive law:

a (b - c) = ab - a c

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

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

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

8 + 2 (3 + 2) - (\frac{10}{2 = 3 ^{2}})

(- 7 x^{7} + 6 x^{9}) (3 e x + 8)

\frac{k ( 4 k + 5 ) + 1}{( 4 k + 1 ) ( 4 k + 5 )}

\frac{4}{5} (20 x - 10)

(3 x - 4 y = 4,) (5 x - 2 y = 9)
