Algebra I
Today we discussedWe reviewed our discussion of simplifying rational expressions. We will use all factoring methods to try to simplify these expressions, including finding the Greatest Common Factor (GCF) or factoring other polynomials. It's also important to recognize that some values will cause our expressions to be undefined, so we must name any excluded values.
Please review the chart on page 286 in your textbook for factoring options.

Today we discussedAs we move on to multiplying rational numbers, today we needed to review changing fractions to mixed numbers and mixed numbers back to improper fractions.
Sections Covered in Textbook
This class discussion supplemented our discussion about multiplying fractions. I felt it was necessary to review some older concepts that are not currently covered in the textbook.
A good online tutorial of how to convert mixed numbers to improper fractions and vice-versa can be found here: http://www.mathsisfun.com/improper-fractions.html
