1. The problem is to find the complete solution of a differential equation or algebraic expression (please specify the exact problem for precise solution). 2. Generally, the complete solution involves finding the general solution plus any particular solution if applicable. 3. For example, if the problem is solving a linear differential equation, the formula is: $$y = y_c + y_p$$ where $y_c$ is the complementary (homogeneous) solution and $y_p$ is a particular solution. 4. To find $y_c$, solve the associated homogeneous equation. 5. To find $y_p$, use methods like undetermined coefficients or variation of parameters depending on the equation. 6. Combine both to get the complete solution. 7. Without the exact problem, this is the general approach to finding a complete solution.
