Our videos and text transcripts will will help refresh your memory of the fundamentals of quadratic equations. Prior to taking the TExES Math 4-8 exam, reexamine the following processes:

  • Solving quadratics by assigning the greatest common factor and using the multiplication property of zero
  • Using the quadratic formula to solve a quadratic expression
  • Applying substitution as a means to solve quadratic equations
  • Factoring quadratic equations by using FOIL in reverse
  • Working with non-standard quadratic expressions
  • Demonstrating parabolas in standard, intercept and vertex form
  • Completing the square and solving quadratics with complex numbers

Let our qualified instructors prepare you for the test by guiding you through each topic. You may pace yourself by jumping to specific video sections with the video tags. Use the text transcripts to go over the concepts you need to review most.

Objectives of the TExES Math 4-8: Quadratic Equations Chapter

The TExES Math 4-8 test will assess your knowledge and comprehension of mathematic concepts and strategies as well as your teaching competencies at the middle school level. It will determine your readiness for educator licensure in Texas. The topics in this chapter may be found in the Patterns and Algebra domain (21% of the test) or the Mathematical Processes and Perspectives domain (10% of the test).

Use our self-check assessments that accompany each lesson to test your understanding of these crucial concepts while also familiarizing yourself with the types of questions you'll actually see on test day. All of the questions on the exam are in multiple-choice form and are computer administered.
