Use the algebra tiles to write the product of (2 - 2x) (3 - 5x)

1 answer

To find the product of \( (2 - 2x)(3 - 5x) \) using algebra tiles, you can follow these steps:

  1. Identify the terms: The expression consists of two binomials:

    • The first binomial is \( 2 - 2x \).
    • The second binomial is \( 3 - 5x \).
  2. Set up the area model: We can represent this product using an area model or algebra tiles, where one binomial is represented along one side of the rectangle and the other along another side.

  3. Draw the rectangle: Create a rectangle divided into areas based on the terms of each binomial:

    • The width of the rectangle would be \( 2 \) (from \( 2 - 2x \)) and \( -2x \).
    • The height of the rectangle would be \( 3 \) and \( -5x \).
  4. Multiply the terms: You now fill in the areas of each section of your rectangle by multiplying the sides:

    • The area for the \( 2 \times 3 \) section is \( 6 \).
    • The area for the \( 2 \times (-5x) \) section is \( -10x \).
    • The area for the \( -2x \times 3 \) section is \( -6x \).
    • The area for the \( -2x \times (-5x) \) section is \( 10x^2 \).
  5. Combine the areas: Now add together the results from each section:

    • Combine like terms:
    • The constant term is \( 6 \).
    • The \( x \) terms are \( -10x - 6x = -16x \).
    • The \( x^2 \) term is \( 10x^2 \).

So, when you combine all the terms, the final product of \( (2 - 2x)(3 - 5x) \) is:

\[ 10x^2 - 16x + 6 \]

This represents the product of the two binomials.
