Question

\(\ \large \frac{dy}{dx} e^{-x}+xe^{-x} \) ?

Answer 1

Is this derivative with first term only??

Answer 2

That's not an equation, it's an expression and so in this state is useless

Answer 3

It is totally useful:

\[-e^{-x} +x \cdot e^{-x} \implies e^{-x}(x-1)\]

Answer 4

Only if you've got the problem.
