3. REVIEW
Represent Polynomials Using Algebra Tiles 3) Represent 3x2 – x 4) Represent 2x2 + x - 3

4. Multiplying Polynomials Using Algebra Tiles
1) Multiply x(x + 3) using Algebra tiles
Measure side lengths
of (x) and (x + 3)
since x and x + 3
are the two factors
Length of x
Length of x
Length
of 3

5. Multiplying Polynomials Using Algebra Tiles
1) Multiply x(x + 3) using Algebra tiles 2) Draw lines to complete the rectangle and each part in the rectangle. x
x + 3

6. Multiplying Polynomials Using Algebra Tiles
1) Multiply x(x + 3) using Algebra tiles 3) Fill in the spaces with the correct Algebra tiles. x
x + 3
Therefore, x(x + 3) = x2 + 3x

7. Multiplying Polynomials
Use the distributive property to check your answer.
x(x + 3) = x2 + 3x

8. Multiplying Binomials Using Algebra Tiles
2) Multiply (x + 2)(x + 4) using Algebra tiles
Measure side lengths
of (x + 2) and (x + 4)
since x + 2 and x + 4
are the two factors
Length of x + 4
Length of
x + 2

9. Multiplying Polynomials Using Algebra Tiles
2) Multiply (x + 2)(x + 4) using Algebra tiles 2) Draw lines to complete the rectangle and each part in the rectangle.
x + 4
x + 2

10. Multiplying Polynomials Using Algebra Tiles
2) Multiply (x + 2)(x + 4) using Algebra tiles 3) Fill in the spaces with the correct Algebra tiles.
x + 4
x + 2
Therefore, (x + 2)(x + 4) = x2 + 6x + 8

11. Multiplying Binomials Using Algebra Tiles
3) Multiply (2x + 1)(x + 2) using Algebra tiles
Measure side lengths
of (2x + 1) and (x + 2)
since 2x + 1 and x + 2
are the two factors
Length of 2x + 1
Length of
x + 2

12. Multiplying Polynomials Using Algebra Tiles
2) Multiply (2x + 1)(x + 2) using Algebra tiles 2) Draw lines to complete the rectangle and each part in the rectangle.
2x + 1
x + 2

13. Multiplying Polynomials Using Algebra Tiles
2) Multiply (2x + 1)(x + 2) using Algebra tiles 3) Fill in the spaces with the correct Algebra tiles.
2x + 1
x + 2
Therefore, (2x + 1)(x + 2) = 2x2 + 5x + 2

14. Multiplying Binomials
4) Multiply (x + 2)(x + 3) using Algebra Tiles
x + 2
Mark the correct length on the sides
x + 3
Fill in the rectangle with the correct Algebra tiles.
Draw lines to complete the rectangle.
Therefore, (x + 2)(x + 3) = x2 + 5x + 6
