Google search syntax to match phrase, excluding search result domains

I'm trying to search in google to:

"Alba Beta" + "Charlie Delta" -excluded (pinterest.com), -excluded (facebook.com)

What I'm trying to achieve here is to find the results that contain the phrase "Alpha Beta" and separately the phrase "Charlie Delta", and to exclude the desired results from pinterest.com Y facebook.com.

What would be the correct syntax for that?
