Hello, this is Isaac Letz and this is my teaching demo video. So I will be doing my teaching demo video over a multiplying polynomials problem and it is one that I have commonly worked with algebra students in the past as a tutor on solving. Um, so here goes my demo. When I'm working with the student, I would typically have them, um, kind of work along the problem as much as they can showing me what they have learned in the class before I would jump into um, doing my own problem, but in the necessary case I would do so and then give them other example problems with different numbers, having me show, having them show me that they, um, have understood it. So when we look at multiplying polynomial at first, it can be a bit scary seeing the different XS and the different numbers, but what we have to remember when viewing a problem like this is that it's really just a simple multiplication problem.

So the way that we perform this multiplication problem actually is an acronym referred to as foil. And this is going to give us the order in which we do the multiplication problem. The F and FOIL stands for first, the O outside, the I inside and the L last. These are pretty easy to identify in the problem. This is our first one of this polynomial and this is our first one of this poral. So these will be multiplied and that will be one of my products, right? So at the end of the problem we are going to add the four products and combine the like terms. So my first product will be from multiplying the first terms. My second will be from the outside. So this is on the outside and this is on the outside. So I multiply my X square plus times my two.
