This research aims to analyze the textbooks of elementary school mathematics, the number of 9th grade of elementary school adopted by public schools and state Mamanguape. We will analyze the two collections approved by the majority of teachers in the municipality of Mamanguape for the number of 9th grade. With regard to content, polynomial function of 2nd degree or quadratic, we analyze the approach of content. The focus of this analysis was to determine if the organization and teaching mathematics relative to these contents in these collections encourage the development of student learning according to Official Documents for Secondary Education (PCNEM, OCEM), the Guide Textbook Program National Textbook approaches and also meets the guidelines proposed by the National Curriculum for Primary Schools (PCN.).
