Understanding Radical Equations
- Radical: An expression with a root, such as √x or ∛x
- Radical equation: An equation in which the variable appears inside a radical
- Extraneous solution: A solution obtained from squaring both sides that does not satisfy the original equation
- Isolating radicals: Step required to simplify and solve the equation
- Squaring both sides: Common method to eliminate square roots, must check for extraneous solutions
The Radical Equations Calculator provides guidance through each of these steps to ensure accurate solutions.
