1. Draw an algebra tile model for the polynomial in simplified form:

Question

8x^2 - 4x -3x^2 + 6 + 2x -7

8 big blue squares, 4 bars, 3 big red squares, 6 little yellow squares, 2 green bars, 7 little red bars;

(is this correct?)

2.Study the diagram of algebra tiles below.

3 big blue squares, 2 big red squares, 4 green bars, 2 little yellow squares.
+
3 big blue squares, 1 big red squares, 2 green bars, 3 red bars, 5 little red squares.

A. Write a polynomial that represents the model.

3x^2-2x^2+4x+2
+ 3x^21x^2+2x-3x-5

B. Simplify the expression above.
x^2+4x+2
+ 2x^2-x-5

( is this correct)
