    3. Checking of assignment
    A. Reviewing previous ACTIVITY:
    lesson or presenting REMEMBER ME? The teacher will guide the students to answer the
    the new lesson following;
    Recall finding the special product in this form:
    ( x + 8) ( x – 8 ) = x2 – 64
    ( 2x + 4) ( 2x – 4) = 4x2 – 16
    ( 3a + 5) ( 3a – 5) = 9a2 – 25
    QUESTIONS:
    1. What have you observe on the product?
    Expected answer: when we multiply two binomials with positive and
    negative signs in between the product has two terms.
    2. What do you call this product?
    Ans. Binomial
    3. Is there a relation between the special product and sum and difference
    of two squares based on the given above?
    Ans. Yes!
    Teacher will process the different responses of the learners

    B. Establishing a Present the Objectives of the lesson:


    purpose for the Factors completely different types of polynomials (difference of two squares)
    lesson

    C. Presenting ACTIVITY: Let’s EXPLORE!


    examples / Examples of Factoring polynomials using sum and difference of two
    instances of the new squares.
    lesson 1. x – 1= (x + 1) (x – 1)
    2. x – y= (x + y) (x – y
    3. x –4 = (x + 2)(x – 2)
    QUESTIONS:
    1. How many factors did you obtain?
    Ans. Two factors
    2. What are your observations based on the factors?
    Expected ans. The factors are the positive square roots of each term.
    3. What is the operation on the first factor? How about the second factor?
    Ans. First factor- positive, second- negative

    E. Developing Mastery

    ACTIVITY: CREATE YOUR OWN!


    Let the learners formulate their own given binomials that can be factored
    using sum and difference of two terms. Let them solve on the board.
    (Answers may vary) Teacher will select volunteer from the class

    F. Finding practical ACITIVITY: GIVE YOUR OWN! Teacher will guide the students to give real
    applications of concepts situation that relates factoring sum and difference of two squares. Example:
    and skills in daily living A 5m x 5m landscaping is to be done in one corner of a 20m x20m garden. Find the
    area of the field that was not affected by the project. (teacher will guide the learner
    in leading the correct answer.

    G. Making generalizations Guide Questions for Generalization:


    and abstractions about the What is a polynomial?
    lesson (Expected answer: Polynomial is an expression of one or more algebraic terms.)
    How can we obtain the factors of polynomials using common monomial factor?
    (Expected answer: through the GCF.
    What concepts have you learned from factoring that can be applied in your daily
    living? (Answer may vary)
    Note: Teacher must correct immediately the wrong response of the learner

    Individual Work
    I. Evaluating learning Self-check!
    Instructions: Factor each of the following polynomials:
    1. a2 – 16 = (a + 4) (a – 4)
    2. 9x2 – 4 = (3x + 2) (3x – 2)
    3. 64c2 – 1 = (8c + 1) (8c – 1)
    4. 100y2 – 49z2 = (10y + 7z) (10y – 7z)
    5. y2 – 81 = (y + 9) (y – 9)
