I know exactly where they are. This cute little quadratic factors.

First, take out a 2. Then note that 2 times 8 is 16 and 2 plus 8 is 10.

Find the roots:
2c%5E2%2B20c%2B32+=+0 Factor a 2 to simplify a bit.
2%28c%5E2%2B10c%2B16%29+=+0 so...
c%5E2%2B10c%2B16+=+0 Factor.
%28c%2B2%29%28c%2B8%29+=+0 Apply the zero product rule:
c%2B2+=+0 or c%2B8+=+0 so then...
highlight%28c+=+-2%29 or highlight%28c+=+-8%29
