Final answer:
It's not possible to provide a specific particular solution (Yp) from the given equation due to confusion in the presentation. Typically, Yp is found using methods like undetermined coefficients, but the correct format for explaining this process is not present.
Step-by-step explanation:
The particular solution (Yp) of a nonhomogeneous differential equation can be found using the method of undetermined coefficients or variation of parameters. In this scenario, the equation given does not match the format that is typically used to illustrate the method, and there seems to be some confusion in the presentation of the problem itself. Thus, a proper Yp is not provided here, but the concept generally involves assuming a form for Yp that resembles the nonhomogeneous part of the equation and then determining the coefficients by plugging it into the original equation and equating coefficients.
