SUMMARY

The differential equation x²y' = 1 - x² + y² - x²y² is analyzed for its solvability using various methods. The equation is confirmed to be neither linear, exact, nor homogeneous, leaving the methods of separation and Bernoulli's differential equation as viable options. The discussion concludes that the equation can indeed be separated after factoring the right-hand side, leading to the form y'/(y² + 1) = -(x² - 1) / x², which allows for further simplification and solution.

Homework Statement


Solve x2y'=1-x2+y2-x2y2

The methods I've learned so far are:
Separable, Linear, Exact, Homogeneous, and substitution for Bernoulli's D.E.

The equation is not linear, exact, or homogeneous. That leaves only two possible methods to use, separate it or get it into the form of a Bernoulli's D.E.. But I don't see how I can do that.
Anyone?

Thanks in advance!

Shouldn't it be separable?x^2 y'=1-x^2+y^2-x^2 y^2
x^2 y' = -(x^2-1)(y^2 + 1)

y'/(y^2 + 1) = -(x^2 - 1) / x^2

And go from there.

x^2 y'=1-x^2+y^2-x^2 y^2
x^2 y' = -(x^2-1)(y^2 + 1)

y'/(y^2 + 1) = -(x^2 - 1) / x^2

And go from there.

Thanks! Didn't realize I can factor the expression on the right.
