If x = a+0 is a singular point of a second-order linear differential equation, then the substitution t=x-a transforms it into a differential equation having t= 0 as a singular point. We then attribute to the original equation at x = a the behavior of the new equation att= 0. Classify (as regular or irregular) the singular points of the following differential equation. (9 x)y" - 2xy' + 3y = 0 Identify the irregular singular points of the given differential equation. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. The differential equation has the irregular singular point(s) x = (Simplify your answer. Use a comma to separate answers as needed.) O B. The differential equation has no irregular singular points.
