The purpose of this study was to determine: 1) the effect of the use of libraries on the results of students 'mathematics learning, 2) the effect of learning motivation on the results of students' mathematics learning, and 3) the effect of the use of libraries and motivation to learn together -Same to the results of students' mathematics learning. This research is a quantitative research by analyzing a simple linear regression and multiple linear regression. The population in this study were students of class X Mathematics Sciences Academic Year 2016/2017. Samples taken as many as 30 students with technique. simple random sampling to obtain research data used two instruments are closed questionnaire documentation. Analysis data on simple linear regression test showed that the use of the library affects the outcome of students 'mathematics learning and learning motivation also affect the results of students' mathematics learning. In the multiple linear regression showed that the there is influence between the use of library and learning motivation on the results of students' mathematics learning.
