DF(X)/X 25X^2+Y

2 answers

gibberish
maybe you mean

df/dx or dy/dx or ∂f/∂x
using implicit/or partial differentiation?

if so, clean it up a bit so we know what you mean.
There's no way the original problem was presented in such a vague way.

We don't mind helping with the answers, but don't expect us to come up with the questions as well !!
