Hi all

 

I am having a very complicated equation that has the form of 

x*y^2/(x+1)+x*(1/(x-2y)^2)=0

 

Of course, the actual equation is more complicate than above. It is just an example. I want to solve the equation in terms of x. And I know that both x and y are real, and they are positive (greater than 0). My question is, how should I specify this when solving the equation?

 

 

PS: I try to run the program to the solve the equation (without specifying that they are real and positive), and at the output, it gave me something like:

"RootOf(y^2+2y+.......)".   What is that "RootOf" means? Square-root or what?
