Algebra I

Today we discussed
We reviewed multiplying polynomials and extended the conversation to include special products:  product of differences, sum of squares and sum of differences.  Then, we moved on to factors and Greatest Common Factor (GCF).

Recall:

Square of a Sum:  (a + b)² = a² + 2ab + b²

Square of a Difference:  (a - b)² = a² - 2ab + b²

Product of Sum & Difference:  (a + b)(a - b) = a² -  b²

Sections Covered in Textbook
1) 6-9: Some Special Products (pages 243-246)
2) 7-1: Factors and Greatest Common Factor (GCF) (pages 256-260)

Pre-Algebra

Today we discussed
We briefly reviewed multiplying powers with the same base and then started our conversation about the various sets of numbers (Natural, Whole, Integers, Rational, Real).  From there we discussed how to turn a fraction into a decimal and a decimal into a fraction.

To turn a decimal into a fraction:
1)  Say it
     2)  Write it
          3) Simplify it!
