### Intro to Algebra II

1. 1. Introduction to Algebra II RAFS Education
2. 2. What is it? <ul><li>Algebra II is the next step up from Algebra I and has the same fundamentals to it. </li></ul><ul><li>It builds upon Algebra and introduces new aspects. </li></ul>
3. 3. Basic Review Example 1) Solve for x. 2x+4=18 Example 2) Find the slope. (Remember y=mx+b) 3y=x+3 Example 3) Solve the expression. |x+5|=15
4. 4. Basic Review Continued <ul><li>Everything used in Algebra I and even geometry are fair game in Algebra II. </li></ul><ul><li>Graphing, solving for x, polynomials, inequalities, functions, and anything else you care to conjure up. </li></ul><ul><li>Think of Algebra I as basic algebra and Algebra II as intermediate algebra. </li></ul>
5. 5. Answers to Examples <ul><li>Ex1) 2x+4=18 </li></ul><ul><ul><li>2x+4=18 (Basic equation) </li></ul></ul><ul><ul><li>2x=14 (Subtracted 4 from both sides) </li></ul></ul><ul><ul><li>x=7 (Divided 2 from both sides) </li></ul></ul>
6. 6. Answers to Examples <ul><li>Ex2) 3y=x+3 </li></ul><ul><ul><li>3y=x+3 (Basic equation) </li></ul></ul><ul><ul><li>y=1/3x+3 (Divided both sides by 3) </li></ul></ul><ul><ul><li>Slope = 1/3 </li></ul></ul>
7. 7. Answers to Examples <ul><li>* (Two equations since it's an absolute value) </li></ul><ul><li>x+5= -15 </li></ul><ul><li>x= -20 </li></ul><ul><li>Ex3) |x+5|=15 </li></ul><ul><ul><li>x+5=15 </li></ul></ul><ul><ul><li>x=10 </li></ul></ul><ul><ul><li>Solution: x=10,-20 </li></ul></ul>
8. 8. What's New? <ul><ul><li>Arithmetic/Geometric Series </li></ul></ul><ul><ul><li>Conics </li></ul></ul><ul><ul><li>Counting Principles </li></ul></ul><ul><ul><li>Logarithms </li></ul></ul><ul><ul><li>Much, much more! </li></ul></ul><ul><ul><li>It's enough to make you dislike math. </li></ul></ul>
9. 9. <ul><ul><li>There's a lot more to introducing Algebra II than this of course. </li></ul></ul><ul><ul><li>But we're sure you don't need an in-depth introduction if you're doing Algebra II. </li></ul></ul><ul><ul><li>Just remember the things you learned in Algebra I. </li></ul></ul>
10. 10. <ul><ul><li>Good Luck! </li></ul></ul>
