(adsbygoogle = window.adsbygoogle || []).push({}); differentiating for "y"

1. The problem statement, all variables and given/known data

I don't quite understand the reason why one can [itex]\frac{d}{dx}[/itex] y^{2}and get 2y [itex]\frac{dy}{dx}[/itex] when using implicit differentiation. Why can one even go as far as to change y^{2}to 2y?

2. Relevant equations

3. The attempt at a solution

I see the chain rule is applied, I just would like to have a good understanding as to why differentiating y^{2}gives 2y [itex]\frac{dy}{dx}[/itex] when using implicit differentiation
