Are you looking for help, or answers to homework?

Answer 5

If you understand like terms, you can work these problems. For example, can you do this: 3a+7b-6a-4b?

Answer 6

help

Answer 7

So, can you do the one I just posted ( 3a+7b-6a-4b), by combining 3a and (-6a), then combining 7b and (-4b)?

Answer 8

I'm trying to help you think this through without just feeding you answers

Answer 9

If you can do this: 3a+7b-6a-4b, then you can do this: 3√10+7√15-6√10–4√15
The only difference is that "a" is now "√10" and "b" is now "√15".
Don't let these problems scare you. You can always substitute simple variables for the radicals, then substitute them back in at the end of the problem.
