Haskell. Where with two definitions

Question

Can I use two "where" with two or more blocks? Something like that:

plus:: Int -> Int -> Int
plus a b = x + y
         where x = f1 a
         where y = f2 b

+3

Leave all but the first where:

plus:: Int -> Int -> Int
plus a b = x + y
         where x = f1 a
               y = f2 b

note that

definitions must match
you should backtrack only with spaces and not behind tabs (some text editors do not use the standard tab tab width driven by ghc to assume that the last line is indented further or less than it actually is; error)
