Square Roots and Simplifying Radicals • By the end of this lesson you will be able to: • Simplify radical expressions and solve perfect square roots
Simplify Radicals Re-write as the product of two whole number factors where one of the factor is a perfect square. 16 is a perfect square
Adding/Subtracting Like Radicals Simplify one or more expressions so that all or most expressions have a like radical. Add or subtract the coefficient of the like radicals
Rationalize the Denominator Eliminate a radical in the denominator by multiplying the numerator and the denominator by the radical in the denominator.
