PLEASE HELP!!! MEDAL!!! How to simply this?? 2√12-√20-√5

Are you sure the question is correct? Usually you have to find a common factor of all three surds, for example 5 goes into 5 and 20 but not 12. If you find a common factor then you simplify each surd so that they all say \[x \sqrt{5}\] then just minus them from eachother.
