I'm gonna solve the equation Y'=0 if Y=x*e^{-0,4x}

2. Relevant equations

3. The attempt at a solution

I can come as far as to Y'=(1-0,4x)*e^{-0,4x}

Where do I go from here?

Can i just write (1-0,4x)*e^{-0,4x}=0 ?

I can solve the easier kinds of these equations, but this one is the hardest of the ones that I have, and I suspect that something like this will show up on a test in the future, so it would be good if I can solve it.

Anyone can help me in the right direction?
