Equations with Radicals Power Property If P and Q are algebraic expressions, then every solution of the equation P= Q is also a solution of the equation P" = Q", for any positive integer n. %3D Solving an Equation Involving Radicals To solve an equation containing radicals, follow these steps. Step 1 Isolate the radical on one side of the equation. Raise each side of the equation to a power that is the same as the index of the radical so that the radical is eliminated. Step 2 If the equation still contains a radical, repeat Steps 1 and 2. Step 3 Solve the resulting equation. Step 4 Check each proposed solution in the original equation. EXAMPLE 2 Solving an Equation Containing Two Radicals Solve 3x+1- Vx+4 = 1. %3D

Algebraic Expressions
In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.
Numbers
Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.
Subtraction
Before we begin to understand the subtraction of algebraic expressions, we need to list out a few things that form the basis of algebra.
