9Final answer:
The student is seeking help in solving a second-order differential equation with variable coefficients, but due to an error or typos in the provided question, a solution cannot be given without the correct information.
Step-by-step explanation:
The student is asking for a particular solution to a second-order differential equation with variable coefficients, specifically for the equation
s equation does not fit into the category of standard differential equations with constant coefficients; therefore, one typically needs to use methods such as variation of parameters or an undetermined coefficients approach to find a particular solution.
Unfortunately, due to an apparent error in the question, I cannot proceed to solve it. The given strings of text and equations are not relevant to this specific problem and seem to be incorrectly formatted or copied incorrectly. Thus, offering a step-by-step solution here is not possible without the correct and complete equation or additional context.
