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.
The parts of this expression are: ) “a” – The ‘index’, or the “root” of the expression. ) “ a ” – The ‘radical’ symbol. ) “ x n ” – The radicand. This expression can be rewritten as a fractional power on ‘ x ’ of the form: x n / a , where a , n∈Z.

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.
Radical Equations. A radical equation is any equation that contains one or more radicals with a variable in the radicand. Following are some examples of radical equations, all of which will be solved in this section: √x − 1 = 5 √2x − 5 + 4 = x 3√x2 + 4 − 2 = 0.
\(\begin{array}{l}{(a+b)^{2}=a^{2}+2 a b+b^{2}} \\ {(a-b)^{2}=a^{2}-2 a b+b^{2}}\end{array}\) 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.
