Tired of knowing exactly how to solve quadratic equations but still getting marked wrong in your online homework or learning management system? You’re not alone!
=====
In this video, we break down the three main methods for solving quadratics — Square Root Property, Quadratic Formula, and Completing the Square — with crystal-clear, step-by-step examples. The real focus? That frustrating final step: simplifying radicals and formatting your exact answers so they match what the LMS expects.
====
We’ll solve problems using the quadratic formula and completing the square, then pause at the “almost there” moments to revisit the essential rules and concepts behind simplifying square roots (including rationalizing denominators, combining like terms, and writing in standard simplified radical form). Whether you’re in Algebra 1, Algebra 2, or prepping for college math, this video will help you go from “I got the solution” to “I entered it correctly and got full credit.”
=====
What You’ll Learn:
• Quick review of the Square Root Property with simple and more complex examples • Full walkthrough of the Quadratic Formula (including the discriminant)
• Completing the Square from start to finish • Deep dive into radical simplification rules that trip up most students
• Common LMS pitfalls and how to avoid them
• Tips for writing exact answers vs. decimal approximations
