(2t–1)(t+5) (page 11) Understand Quadratic Equations; Describe the products of some polynomials Activity 2: (page 12) 1. x2 – 5x + 3 = 0 2. 8k – 3 = 12 3. r2 = 144 4. t2- 7t + 6 = 0 Which of the equations are Identifying equations which are linear and which are not. Identifying which equations are quadratic and not. Understand Quadratic Equations; Identify which of the equations are quadratic and not. Activity 3: Use the situation to answer the questions on page 12. 1. How would you describe the equation formulated? Activity 4: Identify which Write the equations in standard form and identify the values of a, b, and c. Activity 5: Tell whether or not the situations illustrate quadratic equations (page 14) Writing quadratic equations in standard form and identify the values of a, b, and c. Have a deeper understanding of quadratic equations. Concepts and Practicing New Skills#1 linear? Not linear? Describe linear equation. equation is quadratic and which is not. 1. 3m+8=15 2. x2 -5x + 10 = 0 E. Discussing New Concepts and Practicing New Skills#2 Activity 6: Write each quadratic equation in standard form then identify the values of a, b, and c 1. 3x – 2x2 = 7 2. (x =3)((x +4) = 0 3. 2x (x – 3) = 15 How are quadratic equations different form linear equations?
