\frac{d}{d x} (x e^{x - y})

e^{x - y} + e^{x - y} x (1 - \frac{d y}{d x})

Solution steps

\frac{d}{d x} (x e^{x - y})

Apply the Product Rule:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = x, g = e^{x - y}

= \frac{d x}{d x} e^{x - y} + \frac{d}{d x} (e^{x - y}) x

\frac{d x}{d x} = 1

\frac{d}{d x} (e^{x - y}) = e^{x - y} (1 - \frac{d y}{d x})

= 1 \cdot e^{x - y} + e^{x - y} (1 - \frac{d y}{d x}) x

Simplify

= e^{x - y} + e^{x - y} x (1 - \frac{d y}{d x})
