Need help with combining like terms

How do I figure this out...

11+5t^2+t+6t

If anyone can help I would really appreciate it.

I helped BELOW!!!LOL

See the answer below which I posted as a correction to the answer provided by Margie and Dr Phil.
The correct answer to this post
is 5t^2 + 7t + 11 but note the number was -11 in your post below. .
