the general solution

The problem is to solve y"+ 2y'+ 5y= sin(x). You appear to have correctly got the general solution. Yes, to determine a solution, you need to have other information. Typically those will be given y and y' at a specific value of x (an "initial value problem") or given y at two specific values of x (a "boundary value problem").
