## Unit 1 - Review

## 1.1 Review of Factoring

This section is essentially a review of factoring from grade 10 with one exception - factoring out a monomial is not mentioned. I have assumed that you have internalized this method of factoring that was first introduced to you in Math 8 or 9. If you need a review of it, there is "factoring out a monomial" within the second step of the decomposition example.

## 1.2 New Factoring

This section of factoring is likely very new to you. There are four different types but the third type should feel somewhat familiar. It is the "end" of the decomposition that you did in the last section. Because this is essentially new material and there are a lot of steps in some of the processes it would be a good idea to watch the video more than once.

## 1.3 Rationalizing

Again, this section reviews concepts that you covered in earlier Math courses but may not remember. A "conjugate" is just the name for an expression that is exactly like one you already have but you have changed the operation sign. For example, if you have an expression x+4, the conjugate will be x-4. Only the operation sign changes.

## 1.4 Linear Functions

This section reviews linear functions which were a major topic in Math 10. The two important concepts that you need to remember from this section are finding the slope and using the slope to find the equation for a line.
