MATHEMATICS

1. GOOD MORNING!

2. Do you have difficulties in mathematics?

3. SPEED TEST: Perform the indicated operations:   = -39 = 116 = -416 = - 5 = 289

4. Do You Remember These Products? Find each indicated product then answer the questions that follow.

5. Let’s Answer This! a. How did you find each product? b. In finding each product, what mathematics concepts or principles did you apply? Explain how you applied these mathematics concepts or principles. c. How would you described the products obtained? Are the products polynomials? If YES, what common characteristics do these polynomials have?

6. Another Kind of equation!

7. 1. Which of the given equations are linear? Questions: 2. How do you describe linear equations? 3. Which of the given equations are not linear? Why? 4. How are these equations different from those which are linear? 5. What common characteristics do these equations have?

8. A quadratic equation in one variable is a mathematical sentence of degree 2 that can be written in the following standard form. Quadratic equation Where a, b, and c are real numbers and a ≠0 In the equation, is the quadratic term, bx is the linear term and c is the constant term.

9. Write each equation in standard form,then identify the values of a, b and c.

10. Quadratic or Not Quadratic? Identify which of the following equations are quadratic and which are not. If the equation is not quadratic, explain.

11. Set Me to Your Standard! Write each equation in standard form,then identify the values of a, b and c.
