We study the bounded quadratic systems with either two weak foci or a weak focus of order 2. From the first case we obtain (1,1)-configuration of limit cycles, and in the second case we prove that there is no limit cycle surrounding the weak focus of order 2. Also, we unfold the bounded quadratic sy
