How do I properly use '/=' haskell infix operator for xor?

I'm learning haskell and I'm having an issue getting a line of code to work. The error says it is specifically to do with my "/=" operator. Could anyone help me properly use it?

Thank you.

e = filter (\(x, y, _) -> (x `elem` ed) `(/=)` (y `elem` ve)) es

Simply write /= as a normal infix operator:

e = filter (\(x, y, _) -> (x `elem` ed) /= (y `elem` ve)) es
