[2 pts] Consider the differential equation: (a + 2) (x - 3)y" + 3(x - 3)y' - 2(x + 2)y =0 Which of the following correctly describes all singular points of the DE? O Both x = -2 and x - 3 are regular singular points. * = -2 is an irregular singular point, x - 3 is a regular singular point. Both x = -2 and x = 3 are irregular singular points. *= -2 is a regular singular point
