Confused by equations where the variable is hiding under a square root sign (like √(x+2) = 5)? This comprehensive math tutorial shows you exactly how to solve these types of equations, known as radical equations or square root equations, step-by-step!
In this video, you'll learn:
* What radical (square root) equations are.
* The crucial first step: Isolating the square root term.
* How to eliminate the square root by squaring both sides of the equation.
* Solving the resulting linear or quadratic equation.
* Most Importantly: Why you MUST check for extraneous solutions and how to do it.
* Clear, worked-through examples to build your confidence.
This lesson is perfect for students in Algebra 1, Algebra 2, Pre-Calculus, or anyone needing a refresher on solving equations involving square roots. We break down the process simply and highlight common mistakes to avoid, especially regarding extraneous roots.
