  1. Apply Differentiation Rules: We will differentiate each term of the equation with respect to xx, remembering to use the product rule for the term 2xy-2xy and the chain rule for terms involving yy, since yy is a function of xx.
  2. Differentiate Terms: Differentiate y-y with respect to xx to get dydx-\frac{dy}{dx}.
  3. Combine Differentiated Terms: Differentiate 7y3-7y^3 with respect to xx to get 21y2dydx-21y^2\frac{dy}{dx}, using the chain rule.
