Examples, solutions, videos, and worksheets to help Algebra II students learn how to convert expressions to simplest radical form. Understand that the product of conjugate radicals can be viewed as the difference of two squares.
Simplifying radicals involves rewriting the expression so that the radical has no perfect square (or cube, etc.) factors other than 1.
Simplifying Radicals
Example:
√75 = √(25 * 3)
= √25 * √3
= 5√3
Simplifying Using Conjugates
Sometimes, you can simplify a radical expression by multiplying by the conjugate.
The conjugate of a binomial expression is formed by changing the sign between the two terms.
Example:
The conjugate of 5 - √3 is 5 + √3.
(5 - √3) * (5 + √3) = (5² - (√3)²) = 22
Conjugates are often used to rationalize the denominator of a fraction involving radicals. This involves multiplying both the numerator and denominator by the conjugate of the denominator to eliminate the radical from the denominator.
