Rectangle with GCF

Students and I worked on factoring a trinomial that had a common factor.  Notice that the common factor need not come out of the product first as is often demonstrated.  In the top example, you see that the common factor means that there are two duplicate rectangles to be considered.  In the bottom left, we showed that there are at least two correct ways to factor correctly.  In the bottom right, we see a student who factored out the 2 at the start.

Two students and I used our skills to factor three polynomials using tiles and grids.  Notice that the rectangles are the same “shape” for all three. For more information and practice on the is method, see the video below.



Notice how some equations are written in vertex form, others are in standard, and others are in factored form.  Bravo, Paige!
