Review:

Review #1

1) Write the algebraic expression represented by the algebra tiles. 2) What are the factors of this algebraic expression?

Review #2

Use the algebra tiles to square the following binomials, then combine like terms and write the resulting expression. 1) = 4x

2) = 6x

3) =6y

4) = y=4x

Review #3

Form a rectangle with the algebra tiles. What product is represented by the rectangle? Purple, what are the factors of this product? X-Y

Simplify Complicated Expressions:

Record your responses to the following questions.

1) Rewrite and then simplify the algebraic expression.

= 6x-6y/ (3x+3y) (3x+3y) = 6x+3x+3x/ 6y+3y+3y= 12x/12y=0

2) Rewrite and then simplify the algebraic expression.

= (x-y2)*(x+y2)*(4x+4y) / (x-3y) (x+3y) (2x+2y) = X+x+4x+x+x+2x / 2y+ 2y+ 4y+ 3y+3y+2y= 8X/16Y= 4X/8Y= 2X/4Y= 1X/2Y 3) How many different ways do you think there are to write a complicated algebraic expression that simplifies to a single variable x? There are 3 different ways to write complicated algebraic expressions.

4) Write your own complicated algebraic expression that simplifies to a single variable x. Make sure you need at least 2 polynomial identities to simplify it. Then simplify your expression to prove that it simplifies to a single variable x. Factoring

9x^2+27x-3

All are divisible by 3

GCF=3

1/3 (9x^2+27x-3)

9x^2 / 3 + 27x /3 -3/3

= 3x^2 + 9x – 1

9x^2 + 27x – 3= 3 (3x^2 + 9x – 1)

= 9x^2 + 27x – 3 / 3

= (3x^2 + 9x – 1)

= 3X^2 + 9x - 1
