Question 553513: 9r^2-23rs+10s^2
Answer by rapaljer(4671)   (Show Source):
You can put this solution on YOUR website! Did you want to FACTOR this trinomial? If so, then
9r^2 - 23rs + 10s^2
(9r -5s)(r - 2s)
You may need additional help with factoring!! If so, please see my own website. Look in Chapter 2 of Basic Algebra.
I wrote a whole NON-TRADITIONAL explanation of FACTORING in Basic Algebra!! The easiest way to find my explanation is to go to my FREE website using the easy-to-remember and easy-to-spell link www.mathinlivingcolor.com. At the bottom of this page is a link that will take you to my Homepage. Look near the top of this page for the link "Basic, Intermediate, and College Algebra: One Step at a Time", click on "College Algebra." In Basic Algebra, look in Chapter 2 for the sections on factoring, especially "Section 2.06 Advanced Trinomial Factoring." If you have trouble with this, the see the section on "Trinomial Factoring." The lesson is complete with explanations, examples, and exercises with all the answers. You will especially like the "MATH IN LIVING COLOR" sections that go with this. There are also FREE videos of me teaching this topic in my younger years before I retired from teaching. The videos can be found from my Homepage by looking for the link "Rapalje Videos in Living Color". Choose Basic Algebra, and look for the Factoring videos. I think you will find that my explanations are a LOT easier to understand than the traditional textbooks you are probably using.
Happy New Year!! My Email address is rapaljer@seminolestate.edu if you need to contact me!!
