expressions using the GCF. To help the student, write your own example of a rational
expression and demonstrate how to simplify the expression using the GCF.
a. Write a rational expression with a GCF that has both a numeric part and a
variable part. b. Identify the GCF and show how you can simplify your rational expression using
the GCF. c. To help the student remember the procedure, write 2-3 sentences describing
how you simplified your rational expression using the GCF. © K12 Inc.
