Q. Can this differential equation be solved using separation of variables?dxdy=3xy+5yChoose 1 answer:(A) Yes(B) No
Analyze Differential Equation: Analyze the differential equation to determine if it can be written in the form of a product of a function of x and a function of y.
Separate Variables: Attempt to separate the variables by dividing both sides of the equation by y and moving all terms involving y to one side and all terms involving x to the other side.
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.
Factor Out y: The differential equation is dxdy=3xy+5y. To separate variables, we need to factor out y from the square root to see if the remaining expression inside the square root is a function of x alone. We get dxdy=y⋅3x+5.
Separate Variables: Now we have (dxdy)=y⋅3x+5. We can separate the variables by dividing both sides by y and multiplying both sides by dx to get (y1)dy=3x+5dx.
Conclusion: Since we have successfully expressed the differential equation in the form where one side is a function of y and the other side is a function of x, we can conclude that the differential equation can be solved using separation of variables.
