Unfortunately, without having specific information about the given problems, such as the differential equations and solutions provided, it is not possible to provide a detailed answer. However, I can explain the general concept of the method of reduction of order to find a second linearly independent solution.

The method of reduction of order is used when solving a second-order linear homogeneous differential equation when one solution is known. The goal is to find a second solution that is linearly independent from the first solution.

Here are the general steps to apply the method of reduction of order:

  1. Let’s assume that you have found a known solution to the given differential equation. Let’s call this known solution y₁(x).

  2. Express the given known solution in terms of a new function u(x), where y₁(x) = u(x) * v(x).

  3. Differentiate both sides of the equation y₁(x) = u(x) * v(x) with respect to x.

  4. Substitute the resulting expressions into the original differential equation to obtain a new equation involving u(x) and its derivatives.

  5. Solve this new equation for u(x) by simplifying and reducing it to a first-order linear differential equation in u(x).

  6. Solve the first-order linear differential equation to find the function u(x).

  7. Once u(x) is found, substitute it back into the equation y₁(x) = u(x) * v(x) and solve for v(x).

  8. The general solution to the given differential equation will be in the form y(x) = c₁ * y₁(x) + c₂ * y₂(x), where y₂(x) is the second linearly independent solution found using the method of reduction of order, and c₁ and c₂ are constants.

It is important to note that the actual application of the method of reduction of order in each specific problem may have variations and additional steps depending on the form and specifications of the given differential equation.

If you could provide the specific details of one of the problems, such as the given differential equation and the known solution, I would be able to provide a more detailed and tailored explanation of the solution process.
