The purpose of this study is to describe the misconceptions experienced by students in linear combination material. This study is a qualitative descriptive study with a snowball sampling technique by taking 1 subject who experienced misconception in linear combination. The triangulation used in this study is technique triangulation which is a test in the form of description and interview. The result of this study shows that the subject experiences misconception in linear combination which is in the forming process of coefficient matrix. The subject immediately assumes that the coefficients of each polynomial are known as row vectors in coefficient matrix, regardless of its scalar multiplier. This indicates that the subject is too early to resolve linear equation system in which it should be multiplied first by its scalar. Based on this finding, it can be used as an input for development research of textbook whose its teaching material emphasizes certain material, such as linear combination.
