[tex]2xy+y^2-4x=10[/tex]
Homework Equations
The Attempt at a Solution
I am not very good at differentiation, so I haven't got off to a good start, really.
I guess I can differentiate [itex]y^2 and -4x[/itex] "the usual way", but I am kind of stuck with the [itex]2xy[/itex]-part.
I also recon I have to put the equation = 0
