Solve each differential equation. Express the general solution in explicit form. y' = (3x^2 -1) / (3+2y) So, I will skip many steps, because they are easy. However, I am stuck in one of the last ones. y^2 +3y = x^3- x +C y(y+3)= x^3 - x +C I have seen the solution for y, but I don't understand how it is derived. Can someone help?
