Finding where two parametric paths cross?
Just post as another method.
Considering the two parametric equations are polynomials，we can obtain the implicit equation by eliminate the parametric $t$.
Using the function GroebnerBasis.

Problems with finding the real solutions of equation
To see why this happened, we can firstly factor the polynomial in $\mathbb{Q}$.
Factor[x^16 + x^3 + x + 1]

So -1 is a real root. The root …
