is there a question?

also I would outline your initial assumption to help, and as a start look at putting a constant through your DE
 
yes the question is here:

If m(m+9)(m+1)=0, =m-1 and m=-9 aren't the only possible values of m are they?:wink:
 
yes, but web assign for some reason won't accept that answer
 
You have a cubic equation, so there should be 3 roots...you've only listed two of them...
 
what's the other one? m = 0?
 
Yep.
