Introduction to Algebra Tiles

Algebra tiles are a visual representation of algebraic expressions, allowing students to manipulate and understand the properties of polynomials. These tiles are typically colored and labeled to represent different variables and constants. In this article, we will explore whether Cherise correctly represented the product of ${$ (x-2)(x-3)$}$ using algebra tiles.

Representing the Expression ${$ (x-2)(x-3)$}$

To represent the expression ${$ (x-2)(x-3)$}$ using algebra tiles, we need to understand the properties of each tile. The ${$ x$}$-tiles represent the variable ${$ x$}$, while the constant tiles represent the numbers ${ $2\$}$ and ${ $3\$}$ . The negative integer tiles represent the negative values of the constants.

Step 1: Representing the First Factor ${$ (x-2)$}$

To represent the first factor ${$ (x-2)$}$, we need to place an ${$ x$}$-tile and a constant tile labeled ${$ -2$}$ next to each other. This represents the expression ${$ x-2$}$.

Step 2: Representing the Second Factor ${$ (x-3)$}$

To represent the second factor ${$ (x-3)$}$, we need to place an ${$ x$}$-tile and a constant tile labeled ${$ -3$}$ next to each other. This represents the expression ${$ x-3$}$.

Step 3: Multiplying the Factors

To multiply the two factors, we need to multiply the ${$ x$}$-tiles and the constant tiles. When we multiply the ${$ x$}$-tiles, we get ${$ x^2$}$. When we multiply the constant tiles, we get ${$ -2 \times -3 = 6$}$.

Step 4: Combining the Results

To combine the results, we need to place the ${$ x^2$}$-tile and the constant tile labeled ${ $6\$}$ next to each other. This represents the final product of the two factors.

Did Cherise Correctly Represent the Product?

Based on the steps above, we can see that Cherise correctly represented the product of ${$ (x-2)(x-3)$}$ using algebra tiles. She multiplied the ${$ x$}$-tiles and the constant tiles correctly, and combined the results to get the final product.

Conclusion

In conclusion, algebra tiles are a powerful tool for representing and manipulating polynomial expressions. By following the steps outlined above, we can see that Cherise correctly represented the product of ${$ (x-2)(x-3)$}$ using algebra tiles. This demonstrates the importance of understanding the properties of algebra tiles and how to use them to represent and manipulate polynomial expressions.

Common Mistakes When Using Algebra Tiles

When using algebra tiles, it's easy to make mistakes. Here are some common mistakes to watch out for:

Not multiplying the ${$ x$}$-tiles correctly: When multiplying the ${$ x$}$-tiles, make sure to get the correct exponent. In this case, we multiplied the ${$ x$}$-tiles to get ${$ x^2$}$.
Not multiplying the constant tiles correctly: When multiplying the constant tiles, make sure to get the correct product. In this case, we multiplied the constant tiles to get ${$ -2 \times -3 = 6$}$.
Not combining the results correctly: When combining the results, make sure to place the ${$ x^2$}$-tile and the constant tile labeled ${ $6\$}$ next to each other.

Tips for Using Algebra Tiles

Here are some tips for using algebra tiles:

Start with simple expressions: Begin with simple expressions and gradually move on to more complex ones.
Use the correct tiles: Make sure to use the correct tiles for each variable and constant.
Follow the order of operations: Follow the order of operations when multiplying and combining the tiles.
