            The learner demonstrates understanding of key concepts and principles of patterns and algebra (quadratic equations and inequalities, quadratic functions, rational algebraic eqautions, variations, and radicals) and geometry (parallelograms and triangle similarities and basic concepts of trigonometry) as applied – using appropriate technology – in critical thinking, problem solving, reasoning, communicating, making connections, representations, and decision in real life.

I. Objectives: At the end of the quarter, the learners should be able to:

A. demonstrate understanding of key concepts of quadratic equations, inequalities and functions, and rational algebraic equations
