To get the negative answer the unknown must be negative (-0.577)https://community.betfair.com/chit_chat/go/thread/view/94038/30586071/maths-question?post_id=546219619#546219619Dunlaying you are correct. To get the negative answer the unknown must be negative (-0.577)Mon, 14 Sep 2015 13:46:19 -0500Of course a square root can be positive or negative but in this case the answer is negative.Take the original equation and you have a positive multiplied by an unknown equal to a negative.
