Hello!

This is a problem about the general solution of a differential equation.

What we can first do here is separate the variables so that we have the same variable for each side (ex.
dy with the
y term and
dx with the
x term).


(dy)/(dx)=(x-1)/(3y^2)


3y^2dy=x-1dx

Then, we can integrate using the power rule to get rid of the differentiating terms, remember to add the constant of integration, C, to at least one side of the resulting equation.


y^3=(1)/(2)x^2-x+C

Then here, we just solve for
y and we have our general solution.


y=\sqrt[3]{(1)/(2)x^2-x+C}

We can see that answer choice D has an equivalent equation, so answer choice D is the correct answer.

Hope this helps!
