Free Radicals Calculator - Simplify radical expressions using algebraic rules step-by-step.
General Solution Steps: Step 1. Isolate the Radical(s) and identify the index (n). Step 2. Raise both sides of the equation to the “nth” power. Step 3. Use algebraic techniques (i.e. factoring, combining like terms,...) to isolate the variable. Repeat Steps 1 and 2 if necessary. Step 4. Check answers.

1 Radical Equations. An equation that has the variable to be solved for inside a radical is called a radical equation. The algebraic manipulations (described below) needed to solve the equation for the variable can be involved, and may result in extraneous solutions.
A common method for solving radical equations is to raise both sides of an equation to whatever power will eliminate the radical sign from the equation. But be careful: when both sides of an equation are raised to an even power, the possibility exists that extraneous solutions will be introduced.
\(\begin{array}{l}{(a+b)^{2}=a^{2}+2 a b+b^{2}} \\ {(a-b)^{2}=a^{2}-2 a b+b^{2}}\end{array}\) Solve a Radical Equation. Isolate one of the radical terms on one side of the equation. Raise both sides of the equation to the power of the index. Are there any more radicals? If yes, repeat Step 1 and Step 2 again. If no, solve the new equation.
