Factoring with Algebra Tiles

Factoring Polynomials Factoring is the process of writing a polynomial as a product. Algebra tiles can be used to factor polynomials. Use tiles and the frame to represent the problem. Use the tiles to fill in the array so as to form a rectangle inside the frame. Be prepared to use zero pairs to fill in the array.

Factoring Polynomials 3x + 3 2x – 6 (x + 1) = 3 · = 2 · (x – 3)

Factoring Polynomials x2 + 6x + 8 = (x + 2)(x + 4)

Factoring Polynomials x2 – 5x + 6 = (x – 2)(x – 3) Remember: You must form a RECTANGLE out of the polynomial

Factoring Polynomials x2 – x – 6 = (x + 2)(x – 3) This time the polynomial doesn’t form a rectangle, so I have to add “zero pairs” in order to form a rectangle.
