(9.4.2) – Add and subtract radical expressions. Dividing Radicals: When dividing radicals (with the same index), divide under the radical, and then divide in front of the radical (divide any values multiplied times the radicals). Since the denominator has a radical, we have to rationalize the fraction. Dividing Radical Expressions (Rationalizing the Denominator) To divide radical expressions with the same index, we use the quotient rule for radicals. After any simplifying, you need to make sure that there is no radical in the denominator. Ensure that the index of each radical is the same and that the denominator is not zero. As you become more familiar with dividing and simplifying radical expressions, make sure you continue to pay attention to the roots of the radicals that you are dividing.

Since there is no denominator to rationalize, the problem is finished. Example 1: to simplify $(\sqrt{2}-1)(\sqrt{2}+1)$ type (r2 - 1)(r2 + 1) . The quotient rule states that a radical involving a quotient is equal to the quotients of two radicals. Example 2. The only thing you can do is match the radicals with the same index and radicands and addthem together. Dividing Radical Expressions (Rationalizing the Denominator) To divide radical expressions with the same index, we use the quotient rule for radicals. Divide Radical Expressions. A quotient is the answer to a division problem. Since we can't leave the expression with a radical in the denominator, we need to rationalize it, or find something that when multiplied by the denominator will remove the radical. Conjugates & Dividing by Radicals. The quotient property of radicals requires the indices of the radicals to be the same.
