My answers were
1. 34-6x^2, 21x^4/3y
2. 4 is the degree of the polynomail

I had someone else help me with this question but got it wrong.

directrix · Answer

Did you subtract (29x^2 - 7 ) from (21x^4 + 3y - 6x^2 + 34) ?

directrix · Answer

(21x^4 + 3y - 6x^2 + 34) -  (29x^2 - 7 ) =   @Austin1617

anonymous · Answer

Is it 21x^4-35x^2+3y+41 @Directrix ?

directrix · Answer

That is what the "Wolf" says. 

Let's test the answer.

what is the "Wolf"

directrix · Answer

The "Wolf" says yes to the answer for the first part of the question. http://www.wolframalpha.com/input/?i=%28+21x%5E4+%2B+3y+-+6x%5E2+%2B+34%29+-+%2821x%5E4-35x%5E2%2B3y%2B41%29

directrix · Answer

First degree polynomial means that the 21x^4 and the -6x^2 have to go because they are fourth degree and second degree terms, respectively.

The 3y is a degree 1 term. The 34 is of understood degree zero. We can keep it.
