The document provides guidance for solving algebraic expression and rational polynomial exercises. It includes several steps: read the problem until it is understood, note the given data, identify what is being asked, consider each datum and perform the appropriate operation, indicate each result, and write the solution responding to what is asked. It also defines key concepts like algebraic expressions, the distributive law, polynomial ordering, binomial squares, polynomial subtraction, rational expressions, and the domain of rational functions. Methods like synthetic division and factoring common factors are described.
