SUMMARY
The general solution to the second order homogeneous differential equation y'' - y' = 0 can be expressed as y(x) = c1 cosh(x) + c2 sinh(x), where c1 and c2 are arbitrary real constants. The terms "cosh" and "sinh" refer to hyperbolic cosine and hyperbolic sine functions, respectively, defined as cosh(x) = (e^x + e^(-x))/2 and sinh(x) = (e^x - e^(-x))/2. Both functions satisfy the given differential equation, confirming the validity of the proposed solution.
