Question

Is differential equation x^2 * y’ = x* y + y^2

a) linear

b) separable

c) Exact

Answer 1

I made the comment yesterday for the following reasons:

1) the presence of y² makes the equation non-linear

2) the variables are NOT separable

3) the requisite partial derivatives are not equal, i.e. the equation is not exact
