AB - <p>In this paper, we will calculate an integrating factor, first integral, and reduce the order of the non-Linear second-order ODEs , through the <em>λ</em>-symmetry method. Moreover, we compute an integrating factor, first integral and reduce the order for particular cases of this equation.</p>
