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

My response:

With his specific equation, algebra tiles wouldn't be a good tool to use because it would take a very long time to drag 80 squares into the product zone. It would end up taking more time then doing it with the other method and the same is true for other equations with large numbers.

Step-by-step explanation: Sample Response: Algebra tiles would not be a good tool to use to factor the trinomial because you would need to drag an x-squared tile, 18 x-tiles, and 80 plus tiles. That is a total of 99 tiles. It would take a lot of time to drag that many tiles on the board and there might not be enough space to hold all of them. You would also need to determine how to arrange all those tiles to make a rectangle. Since 80 is a multiple of 10, you might recognize that 10 and 8 are the factors that add to 18, which would give you the values to use in the X method.

what grade level is this? need to know so i can look in my old textbooks!

no association

step-by-step explanation:

if you have eyes and you can use them efficiently you can see that it just looks like random dots like do a line of best fit and like they're so spread out it's such a weak association you might as well consider it nonexistent
