You can put this solution on YOUR website! Thank you for asking this question!! I have a LOT of explanation on the topic of FACTORING. More about that later.
In this problem, you need to see if there is a COMMON FACTOR--that is, a number or variable that divides evenly into each of the two terms in this problem. Get the largest common factor, which would be 8. So, factor out the 8, which leaves a 5p in the first term and 4r in the second term.
8(5p - 4r).
For additional help with FACTORING, please see my own website. To find my website, you can click on my tutor name "Rapaljer" anywhere in algebra.com. There you will find a link that takes you to my Homepage. On the Homepage, look for the link "Basic, Intermediate, and College Algebra: One Step at a Time." Choose, "Basic Algebra", and look in "Chapter 2" for "Section 2.03 Factoring the Common Factor." Here you will find my own non-traditional explanation that was written especially for students who have trouble with math. My own students all told me that it was much easier to understand than the traditional textbooks. Now, my entire curriculum from Basic Algebra to College Algebra is all posted on the website FREE!!
There is also a video from my own classes before I retired of me teaching the lesson on FACTORING. You can see this video FREE from my website. On my Homepage, look for the link "Rapalje Videos in Living Color." Choose "Basic Algebra" and look for the video called "Factoring."
If you get tired of Factoring, or if you just plain hate math, then see my "Joke Page", with lots of good clean jokes, all safe for the little ears in your family!!
If you need help with this topic or with other topics, please send me an Email. I'll be glad to help you find the right page on my website to give you the help you need!!
