Let $a(x)=x^6-3x^5+x^4+x^2-3$, and $b(x)=x^4$.
When dividing $a$ by $b$, we can find the unique quotient polynomial $q$ and remainder polynomial $r$ that satisfy the following equation:
$\dfrac{a(x)}{b(x)}=q(x) + \dfrac{r(x)}{b(x)}$,
where the degree of $r(x)$ is less than the degree of $b(x)$.

**What is the remainder, $r(x)$**?
