  1. Analyze Differential Equation: Analyze the differential equation to determine if it can be written in the form of a product of a function of xx and a function of yy.
  2. Separate Variables: Attempt to separate the variables by dividing both sides of the equation by y\sqrt{y} and moving all terms involving yy to one side and all terms involving xx to the other side.
  3. Check Separability: Check if the resulting expression allows for the separation of variables, meaning that each side of the equation depends on only one variable.
  4. Factor Out yy: The differential equation is dydx=3xy+5y\frac{dy}{dx} = \sqrt{3xy + 5y}. To separate variables, we need to factor out yy from the square root to see if the remaining expression inside the square root is a function of xx alone. We get dydx=y3x+5\frac{dy}{dx} = \sqrt{y} \cdot \sqrt{3x + 5}.
  5. Separate Variables: Now we have (dydx)=y3x+5(\frac{dy}{dx}) = \sqrt{y} \cdot \sqrt{3x + 5}. We can separate the variables by dividing both sides by y\sqrt{y} and multiplying both sides by dxdx to get (1y)dy=3x+5dx(\frac{1}{\sqrt{y}}) dy = \sqrt{3x + 5} dx.
  6. Conclusion: Since we have successfully expressed the differential equation in the form where one side is a function of yy and the other side is a function of xx, we can conclude that the differential equation can be solved using separation of variables.
