[d]/[/dx](x*[dy]/[/dx]) = A*x

is that equivalent to saying y'(x) + x*y''(x) = A*x

then use the method of undetermined coefficients to solve it for y?

Just need a start, not the answer. Thanks.

You have an exact derivative on the left side as it stands. Just immediately take an antiderivative to get started.
