Exponential Functions

[Christina82]

This is in my Calculus for Business class...

I have done these before, however I have forgotten

I will attempt to type the problem, if someone knows how to do this, please let me know.

-2xe^-7x + x^2(e^-7x)=0

The answer to this is (0,-9) and I'm not sure how this is....

Thanks,
Christina

Your query is also in Algebra. Please do not double post the same problem in different forums. This is not calculus.

Sorry.

Sorry. I'm a whole 30 minutes old here. If it's not calculus, then why is it in my Calculus for Business class? I posted it twice, because I wasn't certain which forum was correct, since I've seen it before in Algebra, but it's now in my Calculus class, I have just forgotten how to do it. Thanks!

That's OK. Just a heads up. This is probably in calculus because they want to make sure you can factor and/or solve an algebraic equation before you start calculus problems.
