Answer

The sum of the polynomials is .

Solution

Certainly! Let’s use the concept of algebra tiles to add the two polynomials and .

Step 1: Represent Each Polynomial with Algebra Tiles

  1. First Polynomial:
    • 7 tiles
    • -3 tiles
    • +6 unit tiles
  2. Second Polynomial:
    • 10 tiles
    • -7 unit tiles

Step 2: Combine Like Terms

When adding polynomials, like terms (terms with the same variable and exponent) are combined by adding their coefficients.
  1. Terms:
    • Only from the first polynomial: 7 tiles
    • Total:
  2. Terms:
    • From the first polynomial: -3 tiles
    • From the second polynomial: +10 tiles
    • Combined:
  3. Constant (Unit) Terms:
    • From the first polynomial: +6 units
    • From the second polynomial: -7 units
    • Combined:

Step 3: Write the Resulting Polynomial

After combining like terms, the sum of the two polynomials is:

Visual Summary with Algebra Tiles

  • Tiles: 7 (no combining needed)
  • Tiles:
  • Unit Tiles:
So, the final combined polynomial is:

Bonus Knowledge

To solve using algebra tiles, first represent each term with tiles. For , use 7 large square tiles. For , use 3 negative x-tiles, and for , use 6 positive unit tiles. Then, for the term, you would use 10 positive x-tiles, and for the , use 7 negative unit tiles.
Next, combine like terms:
  • For tiles, you have 7.
  • For tiles, you combine .
  • For the constant tiles, you combine .
So, the resulting expression from the tiles is .
It’s like balancing out a fun tile puzzle!
