How to factor complicated trinomials using Algebra Tiles
First, remember to write down what you think should be noticed about the product of the diagonals.
Draw the Algebra Tiles, then write the polynomial in factored form for the following polynomials:
1. 
2. 
Now multiply the diagonals, what do you notice?
Were you right about the pattern?
Here is where the fun begins!
Use the method in the video to draw a rectangle and using the product of the diagonals to help find the 2 sections of x-blocks. Then factor out the GCF in each row and column to find the length and width of the rectangle.
