Feb 9 and 10 Solving Square Root Equations

A radical equation is an equation that has a variable in a radicand (or a variable with a fractional exponent) If the radical has index 2, the equation is a square root equation.

Steps for solving square root equations: 1. Isolate the radical 2. Square both sides 3. Solve for the variable 4. Check for extraneous solutions Extraneous solutions: extra solutions that do not satisfy the original equation

What is important to remember as you solve square root equations?
