Solve the given initial-value problem. (x + y)^2 dx + (2xy + x^2 - 8) dy = 0, y(1) = 1

Notice that

so the ODE is exact, and we can look for a solution of the form . Differentiating both sides gives

so that the solution to the ODE is

Given that , we have

so that the particular solution is

answer: r there any options?
