ok here is the other problem...
dy/dx = (y^2+y)/(x^2+x)
i see that it is separable, but could it also be Bernoulli because of the y squared?
Yes, it is also a Bernouilli equation.

Don't worry, we quickly make another book.
The equation is equivalent to:
That is, it has the form (Bernouilli equation).
