expand e^{4(-x-y)}-2e^{2(-x-y)+2xy}

expand

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

e^{- 4 x - 4 y} - 2 e^{- 2 x - 2 y + 2 x y}

Solution steps

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

Expand

4 (- x - y) : - 4 x - 4 y

= e^{- 4 x - 4 y} - 2 e^{2 x y + 2 (- x - y)}

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

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