![]() ![]() The first thing you're going to do when you're given a trinomial where a is 1 there it is right there that's the one and you're asked to write it in factored form, first thing you're going to do is look for two numbers whose sum is the middle term which is b, there it is, we want sum to be that and whose product is the constant term. Also look 12, this number here, is the product of my two constants that is super important that pattern is how you solve these problems. The first thing I want you to notice is that this number right here is the sum of my two constants 3+4 gave me 7. ![]() Let me show you a couple of things to notice. You already know how to do that the other way around, if you're given this, you could FOIL or use an area model to find out this. You're going to be given a trinomial and asked to write it like this. You're going to be given a problem like this and asked to write it in it's factored form. When a=1, there's a couple of steps you want to do but first I want to show you an example. ![]() Sometimes this is written with an a right there and we're talking about when a=1. In these lessons we're going to be looking at how to factor when it looks like x squared plus bx+c. Factoring is one of the most important skills you're going to learn in your Algebra One course and it's going to show up through the rest of your Math career so it's really important you focus on these times in your school while you're learning how to factor. ![]()
