The analysis of dynamical systems has been a topic of great interest for researches mathematical sciences for a long times. The implementation of several devices and tools have been useful in the finding of solutions as well to describe common behaviors of parametric families of these systems. In this paper we study deeply a particular parametric family of differential equations, the so-called \emph{Linear Polyanin-Zaitsev Vector Field}, which has been introduced in a general case, in the previous paper by the same authors, as a correction of a family presented in the classical book of Polyanin and Zaitsev. Linear Polyanin-Zaitsev Vector Field is transformed into a Li\'enard equation and in particular we obtain the Van Der Pol equation. We present some algebraic and qualitative results to illustrate some interactions between algebra and the qualitative theory of differential equations in this parametric family.
