In this module, you'll learn all of the concepts, techniques and strategies needed to answer algebra and equation-solving questions on the GRE. In particular, this module covers:

 Simplifying algebraic expressions Expanding expressions 3 types of factoring Basic equations Equations with fractions Quadratic equations Systems of equations Equations with exponents Equations with square roots Equations with absolute values Strange operator questions 3 types of inequalities The coordinate plane Equations of lines Graphs of quadratics

### Two ways to prepare

Beneath most of the video lessons below, you’ll find a Reinforcement Activities box containing practice questions that are specifically related to the concepts covered in that lesson (e.g., the lesson on inequalities). With this lesson format, you have two study options:

• Watch the video lesson first and then reinforce your learning by answering several related questions, or…
• Tackle the practice questions first and watch the lesson only if you need help with the concepts the practice questions test

For more on this learning strategy, read the “How to Beat the GRE” section of our course overview page.
