Why might algebra tiles not be a good tool to use to factor x2 + 18x + 80? Explain.

Answer:

Algebra tiles would not be a good tool because the numbers in the trinomial are quite large. Factoring x^2 + 18x + 80 would require one x^2 tile, 18 x-tiles, and 80 unit tiles, for a total of 99 tiles. Managing and arranging that many tiles into a rectangle would be time-consuming and difficult to fit in a workspace.

What did you include in your response? Check all that apply.

A
There are a lot of tiles to drag onto the board.
B
You would need to create a rectangle from 99 tiles.
C
80 is a multiple of 10, so it has factors of 10 and 8, which add to 18.
