Abstract
The purpose of this study is to understand students mistakes in using the cross method to factorize the squared form. Eight quadratic form factoring is given to students to obtain student learning barrier data. The data were analysed in accordance with the phase of the cross method, followed by the interview to validate the alleged category of learning obstacle types that occurred in each student. The results of this study indicate that the obstacle learning that many students experience using the cross method is didactical obstacle which is one example of the mistake that students fact squared form by not involving variable x.
