Every positive number has two square roots.
The square roots of  67  are  8.185... (rounded) and  -8.185... (rounded) .
Both are irrational numbers, so they can't be completely written down
with digits.  No matter how many decimal places I write, it can never be 
enough, because these decimals go on forever and never end.
        
                    
             
        
        
        
Distribute the 5 to the (2+y). Parenthisis always come first. after that combine the 5y and the -y. you should end up with 2-(+4y) +2. add the -2 and +2. you should be left with 4y
        
             
        
        
        
The answer of that is called a compatible number. I hope this helps! :)
