In this lesson you will learn Operations with Radical Expressions. First, you will review Properties of Radicals before moving into Simplifying Radical Expressions. Then, you will cover Rationalizing Denominators, Conjugate Radical Expressions, Adding and Subtracting Radicals, and Multiplying Radicals. This lecture ends with a series of video examples.
To simplify a
square root expression, extract all perfect squares from the
When adding or
subtracting, combine only like radicals.
To rationalize a
radical expression with a binomial denominator, multiply the
numerator and denominator by the conjugate of the denominator.
