Hi, I might be making an obvious error, but can't you write the answer as r+y-x. Or is there a reason why u cannot remove the square root. Thanks

Square roots could be + or -

Basically if you sqare root it from the start, it would either be - or + Because you are finding a length, it will have to be positive
