# Algebra 2

## Introduction

This page contains resources that may be of interest to students studying Algebra 2 (second year Algebra). The number of resources on this page will grow as additional items are developed. If you have any questions or special requests, please contact Earl at mathguy.us@gmail.com.

## Handbooks

- Pre‐Algebra Handbook version 2.4 – Covers math subjects for grades 6, 7 and 8.
- Algebra and PreCalculus Handbook version 2.9b – Covers two years of Algebra and some Pre-Calculus.

For more information on the handbooks, including download instructions, go to the Math Handbook page.

## Android Apps

- Number Explorer App version 1.1 – Explore numbers: prime factorization, divisibility, find all factors, greatest common factor and least common multiple.

- Quadratic Function App version 2.3 – Work with quadratic functions: various forms, complete the square, get decimal and exact (real or complex) zeros, transformations, domain, range, axis of symmetry, intercepts, end behavior, graph the function and more.

## Sample Tests and Solutions

The value of reviewing these sample problems and solutions is twofold. The more obvious benefit relates to problems that a student has difficulty solving themselves; a solution is provided. Less obvious is the set of techniques used in our solutions; some of the techniques used on the sample problems may not be taught in the classroom. We concentrate on efficient solutions and shortcuts; so a review of the solved problems may present new techniques that enable a student to be more efficient in their approach to solving problems.

Note that Sample Tests are provided for multiple years. The units tend to overlap somewhat, so be careful that you are looking at the tests for the subjects you want.
