So I was making a new character called Fleur who is a white dragon heritage blood hunter and I rolled 10, 13, 4, 6, 12, and 17 for ability scores, where should I assign each one?

Edit: Actually, I also have a second available set of 7, 8, 10, 5, 14, and 12 which set is better and where should I assign each score from the set I use?

You may want to ask in Tips & Tactics instead. I think the discussion there is more viable.

 how did you get four and six😂😂

Those are both.... Bad. Both of those spreads are bad. My advice, if still applicable, would be to ask if you can just take the Standard Array. 

Both of those spreads have almost more negative modifiers than positive.
