A new guideline for simplifying radicals is introduced: the terms in a fully-simplified radical expression must have no common radical factors. Simplifying a radical expression by adding or subtracting common radical factors is illustrated.
Simplifying a radical by multiplying first to get a perfect square in the radicand.
The process of simplifying to find a common radical factor is demonstrated.
Instances are demonstrated where simplifying radicals before multiplying are indicated.
Illustrations of the rule for multiplying radicals: the square root of a times the square root of b equals the square root of the product a times b.
Simplifying rational expressions is like reducing rational numbers. First fully factor the numerator and denominator and then cancel all the common factors. The process is illustrated step by step.
