Using the substitution u = ln(x), find the general solution of the differential equation y = x^2*(d^2(y)/dx^2) + x(dy/dx) + y = 0

dy/dx = (dy/du) (1/x), d^2(y)/dx^2 = (d^2(y)/du^2) (1/(x^2)) - (dy/du)*(1/(x^2)) (x^2) ( (d^2(y)/du^2) (1/(x^2)) - (dy/du) (1/(x^2)) ) + x (dy/du)*(1/x) + y = 0 d^2(y)/du^2 - dy/du + dy/du + y = 0 d^2(y)/du^...
