Use the following to review the topics you experienced difficulties with in the Are You Ready? section.

Search the Internet for a definition of perfect square trinomials. One way to obtain the definition for any word is to use a search engine. When there are several words in an expression, use quotation marks. For example, you can enter “perfect square trinomial” to find this definition.
Go to Module 3: Lesson 5, page 3 in Mathematics 10C Learn EveryWare. Near the bottom of this page is the section “Factoring Perfect Square Trinomials.” You can find the definition in this section as well as an example showing how you can identify and factor a perfect square trinomial.
Go to Module 4: Lesson 4, page 4 in Mathematics 10C Learn EveryWare. Review “Example 1” and “Example 2” to see several methods of converting entire radicals to simplified mixed radicals.
Practise converting quadratic functions into vertex form by completing the square in Completing the Square.
