About Radical Equations
Radical equations contain variables under radical symbols. To solve: isolate the radical, raise both sides to eliminate it, solve for the variable, and always check for extraneous solutions.
Frequently Asked Questions
What is an extraneous solution?
A solution that emerges algebraically but doesn't satisfy the original equation. Always check your solutions!
Why check solutions?
Squaring both sides can introduce false solutions. Verification ensures the answer is valid.
Can √x equal a negative number?
No. The principal square root is always non-negative for real numbers.
