This worksheet is designed to replace a lecture on the topic of factoring trinomials, particularly when the leading coefficient is not 1, or when there is a GCF greater than 1. For instance, this worksheet will walk students through the process of factoring the following polynomials:
10x^3-35x^2-20x = 5x(x-4)(2x+1)
10x^2-250 = 10(x-5)(x+5)
I start out class with a 15-minute "mini-lesson," giving my students some basic examples of what today's lesson will be about. Once the mini-lesson is over, I have them get to work within their groups on this worksheet.
I use this activity within cooperative groups, and I circulate to make sure they are getting the purpose of the questions.
The file includes spiral review problems.
This worksheet is intended to be written on directly.
Please download the pdf preview file first, so you can see exactly what's included; the product file is a word document, which you may personalize for your students.
