Answer 3

so those are the simplified version of the roots. ill explain how I got those through the messaging but after that since only common roots can be added and subtractes we can do this:
9root2+20root2=29root2
-4root10-3root10=-7root10
so the final answer should be 29root2-7root2 which is the same thing as -7root2+29root2
