Slip and Slide Factoring

Section 2.6 General Math 2

by Katey Burner

​Factoring when a>1

• ​For this section, we will focus on the slip n slide method to factoring

• ​You can also create a table and test values as in the book but I have found the slip n slide to be much easier to remember the steps to and to put into practice

• ​When do we use this method? When we have a trinomial after pulling out the GCF and a is not 1. This will be very important when solving equations later
