“…Therefore, the authors worked on both topics separately for the same system. For example, the authors studied meromorphic first integral in Maciejewski and Przybylska [
11] and Shi and Li [
12], while in Llibre and Valls [
13, 14] respectively, they studied the Darboux integrability. The authors Maciejewski and Szumiski [
9] used differential Galois theory to investigate the integrability of system () for both cases
and
under the condition
