Alternate Methods to solve Undetermined Coefficients

Hi,

The traditional method to solving 2nd order non-homogeneous linear ODE's is to solve for the 1st and 2nd d/dt of yp. However I have seen an alternate method that takes the denominator of the ODE and places it in the numerator, then squares the denominator and you multiply this resultant by the input "r(t)"...which results in the same coefficients as the traditional method.

Anyone here familiar with this method?
