### Re: Adding and Subtracting Polynomials

I pretty much lost what you guys were talking about..

So, I'm just going to post a revised version of #17..

17.

I really hope that's correct..
If it isn't would someone just tell me the correct answer?

I'm just here to get some help with an online math course I'm taking.

### Re: Adding and Subtracting Polynomials

Sorry but it is not correct.

It is very hard to see where you are making mistakes when you only post your answer and not all the steps in between!

original posting of question post #18

Clear the brackets:
Note all the sign changes from the second bracket.

Collect like terms:

Simplify:

Hope that helps,
