Ch 7: Quadratic Equations

About This Chapter

Review the elements of quadratic equations and other algebraic math problems to prepare for the 2014 GED Mathematical Reasoning exam. Video lessons and self-assessment quizzes integrate all of the material of the mathematical reasoning section in a simple and concise manner.

2014 GED Mathematical Reasoning: Quadratic Equations - Chapter Summary

Learn to solve quadratic equations using a variety of methods through our 2014 GED Mathematical Reasoning lessons. The chapter teaches you important formulas, factoring techniques and binomial uses when presented with quadratic math problems. Lessons cover topics on:

  • Greatest common factors
  • Multiplication properties
  • Quadratic formulas
  • Non-standard quadratics
  • Quadratic inequalities

The lessons on quadratic equations come with a variety of example math problems and formulas. You'll be able to take self-assessment quizzes to test your learning of each lesson. These short video lessons break the material down in an easy-to-understand manner that can help you pass the 2014 GED Mathematical Reasoning exam.

2014 GED Mathematical Reasoning Objectives

The 2014 GED exam replaced the 2002 GED exam in January of 2014. This new exam is entirely computer based and now adheres to the Common Core State Standards. The mathematical reasoning exam is one of four tests that make up the 2014 GED exam. Algebraic problem solving (which can include quadratic equations) constitutes 55% of the mathematical reasoning exam. The chapter's lessons explore topics that you can expect to find on the actual 2014 GED Mathematical Reasoning exam. Some of the objectives include:

  • Defining quadratic equations and their role in algebra
  • Showing how quadratic equations can result in two different solutions
  • Assigning a greatest common factor to solve quadratic equations
  • Using the quadratic formula to solve quadratic equations
  • Solving quadratics that are not written in standard form
  • Figuring out quadratic inequalities using two binomials

The mathematical reasoning section of the 2014 GED must be completed in 90 minutes and consists of two parts. The first part is composed of five questions that you must answer without the assistance of a calculator. The second section allows the use of calculators. The exam includes a combination of multiple choice, fill-in-the-blank, drag-and-drop and hot spot questions.
