Question:

Let α(x) be an integrating factor for y' + P(x)y = Q(x). The differential equation y' + P(x)y = 0 is called the associated homogeneous equation.
(a) Show that y = 1/α(x) is a solution of the associated homogeneous equation.
(b) Show that if y = ƒ(x) is a particular solution of y' + P(x)y = Q(x), then ƒ(x) + C/α(x) is also a solution for any constant C.
