In summary, an IVP for an ODE is a mathematical problem that involves finding a solution to an ordinary differential equation, given a set of initial conditions. To check the validity of the solution, you can plug it into the original equation and initial conditions. This involves using methods such as substitution and differentiation. Some common mistakes to avoid when checking the solution include forgetting to substitute into initial conditions and not paying attention to the order of operations. Checking the solution is important to ensure accuracy and catch any errors.

Homework Statement


I've got an IVP where,
3xy+y2+(x2+xy)y'=0, y(1)=0

The Attempt at a Solution


I've solved to get,
x2y(x+[itex]\frac{1}{2}[/itex]y)=0

Is it correct to say,
x=0 or y=0 or y=-2x,
Since y= 0 is the only solution that fits y(1)=0, then
y=0 [itex]\forall[/itex]x

I didn't check your solution. But in any case, x=0 wouldn't be a solution. Otherwise, assuming your work is OK, yes.
