question answer key

I have a question on the answer key:

For the recurrence relation problem (#5), isn't the characteristic equation supposed to be r^2+2r+1=0 because of the negatives in the original recurrence relation?
***********************
Yes, my bad.  This would change the answer to -n(-1)^n.
