Partial Derivative help

    Partial Derivative help!!

    Find the first partial derivatives of f(x,y)=(4x+2y)/(4x−2y) at the point (x,y) = (2, 1).

    My professor never taught us how to do this so I have no idea where to start. Any help would be appreciated.

    Derivatives yes, partial derivatives with a quotient, no
