Date: 1.6(a) Notes: Factoring ax² + bx + c Lesson Objective: Factor trinomials of the form ax² + bx + c. CCSS: A.SSE.3a, A.REI.4b You will need: algebra tiles This is Jeopardy!!!: This is the box and the product that represents (x – 3)(x + 2).

Lesson 1: Using Algebra Tiles to Factor Trinomials Using the Algebra Tiles to Factor: 1)Get the number of “a” x² tiles, “b” x tiles, “c” +1 or -1 tiles that are in the polynomial. 2)Set up the x² tiles and the +1 or -1 tiles to make the opposite corners of a box. 3)Split up the “b” tiles to fit in the box.
