In this paper, we consider a general quasi-differential expression
of order n with complex coefficients and
its formal adjoint 
in the space 
We show in the case of one singular
end-point and under suitable conditions on the function 
that all solutions of general
quasi-integro differential equation 
are in 
for all 
provided that all solutions of the
homogeneous differential equations 
and 
are in 
quasi-differential expressions, regular and singular endpoints,
minimal and maximal operators, quasi-differential operators in
quasi-integro differential equations and
their solutions, boundedness of solutions.
