$\displaystyle

$\displaystyle \frac{d}{dx}[x^2y]=\frac{d}{dx}[x]+\frac{d}{dx}[y^2]$ __Good__

$\displaystyle 2xy\frac{dy}{dx}[y]=x+\frac{dy}{dx}[2y]$ Product rule on left hand side... and, what is the derivative of x with respect to x?

$\displaystyle

\frac{dy}{dx}(y-2y)=x-2xy$

$\displaystyle

\frac{dy}{dx}=\frac{x-2xy}{y-2y}$

Did I do it right?
