I. OBJECTIVES
A. Content Standard The learner demonstrates understanding of key concepts of factors of
polynomials, rational algebraic expressions, linear equations and
inequalities in two variables, systems of linear equations and inequalities
in two variables and linear functions.
B. Performance Standard The learner is able to formulate real-life problems involving factors of
polynomials, rational algebraic expressions, linear equations and
inequalities in two variables, systems of linear equations and inequalities
in two variables and linear functions, and solve these problems accurately
using a variety of strategies.
