Thanks for your reply Alvaro.  If I can rearrange the nasty equation into a polynomial in t, then yes I can easily find the roots of it.  The difficulty is in automatically calculating the coefficients of this polynomial, given that it is a summation of terms such as "a_N*(a_x+b_x*t)^N" which would effect the coefficients for ALL terms less than N.

I think that implicitizing the equation might just come down to constructing an appropriate matrix and taking the determinant, after which point I'd have two parametric equations with two unknown parameters, should should be solvable...so I'm not sure which approach is actually easier
