Give an example of two polynomials of degree 9 whose sum has degree 4. I have no clue where to start with this. I don't know if I am supposed to make the factors cancel out.

That satisfies all the conditions doesn't it? If you

**want**to be more complicated, make up any two 9th degree polynomials such that, when you add, all terms with power greater than 4 cancel but the terms with power 4 do not.

Your misunderstanding may have to do with thinking that**factors**have to cancel. That won't happen when you are**adding**polynomials. - October 5th 2012, 09:54 AMEraser147Re: Give an example of two polynomials
Well, thanks guys.
