Besides this, many of my exercises are solved IN COLOR in the MATH IN LIVING COLOR pages that go with this.
In addition to my written explanations of this topic, there is a video explanation from my own classes from before I retired. All of this is FREE if you have RealPlayer. If you don't have RealPlayer, then it is a FREE download.
I have many other topics from Basic, Intermediate, and College Algebra that are explained in detail, with many of these topics explained on video as well. Everything on the website is FREE.
