Find zeros of f(x) = xe^x + 8e^x

You did not post your work, so I cannot comment on what you might have done wrongly.

My first step would be to factor x·e^x + 8·e^x because that will make the solution apparent. Remember, e^x is never zero or negative.

Please show what you tried, if you need more help. :cool:

What do you mean by "getting errors"? Are you trying to plug something into your calculator?

When you reply, please include a clear listing of your steps in at least one of your attempts, starting with setting things equal to zero and then factoring. Thank you!

"zeros" Are you SURE there is more than one?
