Your derivative should have been 64x2x264x2
The minus sign coming from the derivative of (x2)
Setting the derivative to zero,
64x2x264x2=0 multiply both terms by 64x2
(64x2)x2=0
64=2x2
32=x2
x=+4.2

Construct all rational functions f (quotients of polynomials) in C such that (f)=6[0]4[5], where (f) is the divisor of the function f.
My answer/attempt: From my understanding of divisors, there seems to be exactly one function, namely, f(z)=z6(z5)4.
1.Are there any other functions with this divisor? If not, why?
2.If we restrict ourselves to divisors of rational functions only, then if we are given a divisor of a on C, does there exists a unique rational function f with (f)=?

Let f:XP1 be a rational function of degree d2 on a curve X.
Let n2 be a divisor of d. Does there exist a curve Y with a rational function g:YP1 of degree n such that f factors through g
Can we factor f in some sense?

In Hartshorne's Algebraic Geometry the function field K(Y) of a variety Y is defined as the set of equivalence classes with f being a regular function on the open subset U. We have = if f and g agree on UV.
How does one evaluate a "rational function on Y'' f? Is it f(P) using the Evaluation map for polynomials? In this case, I don't see that this is well defined: Let PUV and =, then g(P) might not even be defined!
