  1. Differentiate Equation: Differentiate both sides of the equation with respect to xx, remembering to use the product rule for terms involving both xx and yy, and the chain rule for terms involving yy since yy is a function of xx.
  2. Left Side Derivative: Differentiate the left side of the equation. The derivative of 5x2y4-5x^2y^4 with respect to xx is 10xy420x2y3dydx-10xy^4 - 20x^2y^3\frac{dy}{dx} using the product rule. The derivative of 4x2y3-4x^2y^3 with respect to xx is 8xy312x2y2dydx-8xy^3 - 12x^2y^2\frac{dy}{dx} using the product rule.
  3. Right Side Derivative: Differentiate the right side of the equation. The derivative of 33 with respect to xx is 00, and the derivative of 2x-2x with respect to xx is 2-2.
  4. Write Differentiated Equation: Write down the differentiated equation from Steps 22 and 33: 10xy420x2y3dydx8xy312x2y2dydx=2-10x y^4 - 20x^2 y^3 \frac{dy}{dx} - 8x y^3 - 12x^2 y^2 \frac{dy}{dx} = -2.
  5. Collect Terms: Collect all terms involving dydx\frac{dy}{dx} on one side and move all other terms to the opposite side. This gives us 20x2y3dydx12x2y2dydx=2+10xy4+8xy3-20x^2y^3\frac{dy}{dx} - 12x^2y^2\frac{dy}{dx} = -2 + 10xy^4 + 8xy^3.
  6. Factor Out (dydx):</b>Factorout$(dydx)(\frac{dy}{dx}):</b> Factor out \$(\frac{dy}{dx}) from the left side of the equation to get (dydx)(20x2y312x2y2)=2+10xy4+8xy3(\frac{dy}{dx})(-20x^2y^3 - 12x^2y^2) = -2 + 10xy^4 + 8xy^3.
  7. Solve for (dydx):</b>Solvefor$(dydx)(\frac{dy}{dx}):</b> Solve for \$(\frac{dy}{dx}) by dividing both sides of the equation by (20x2y312x2y2)(-20x^2y^3 - 12x^2y^2). This gives us (dydx)=2+10xy4+8xy320x2y312x2y2(\frac{dy}{dx}) = \frac{-2 + 10xy^4 + 8xy^3}{-20x^2y^3 - 12x^2y^2}.
  8. Simplify (dydx):</b>Simplifytheexpressionfor$(dydx)(\frac{dy}{dx}):</b> Simplify the expression for \$(\frac{dy}{dx}) if possible. In this case, we can factor out an xx from the numerator and an x2y2x^2y^2 from the denominator to get (dydx)=2/x+10y4+8y320xy312y2(\frac{dy}{dx}) = \frac{-2/x + 10y^4 + 8y^3}{-20xy^3 - 12y^2}.
