please help me

Based on the polynomial given, we can assume that the degrees of $p(x)$ and $q(x)$ is $4$.

And since we have no other terms like $x^2$ or $x^6$, we can assume that  $p(x)$ is in the form $x^4+A$  for an integer $A$, and that $q(x)$ is in the form $x^4+B$  for any integer $B$.

Thus, expanding, we get $x^8+(A+B)x^4+AB$. From this, we know that $A+B=98$ and $AB=1$.

Fortunately, we don't need to find $A$ and $B$. What we are trying to find is $2x^4+(A+B)$, which, after we plug in things, we get $2+98=\boxed{100}$, which is a perfect, round, number to end the problem.

I get the following:

(Note to billyzhang:  The question specifies integer coefficients, which your A and B are not.)
