Second order differential equation form

[negation]

A second order differential equation form d²y/dx² = f(x,y,dx/dy)

How do I read the language on the right hand side?

The righthand side is some function of x, y, and dy/dx. For example, it could be x²y - 3dy/dx.

I know that. I should have been more explicit. How does the RHS (expand?) to the LHS?

What Mark44 said is all you can say. How you "expand" it or if you can depends upon the exact function. And it certainly does not expand "to" the LHS, any more than the "f(x)" in "y= f(x)" expands to "y".
