Question 971138: 12 square root 60 - 14 square root 21

You can put this solution on YOUR website!
sqrt (60)=sqrt (4)* sqrt (15) = 2 sqrt (15)
sqrt (21) does not break down
24 sqrt (15)-14 sqrt (21)
2[12 sqrt (15)-7 sqrt (21)}
I don't break them up into sqrt (3) and sqrt 5) or sqrt (3) sqrt (7). I want only perfect squares.
