6.3 BINOMIAL RADICAL EXPRESSIONS Algebra II w/ trig

I. Combining Radical Expressions: Sums and Differences A. What is the simplified form of each expression? 1. 2. 3.

Some problems requires simplifying before combining. B. Simplify. 1.2. 3.4.

II. Multiplying Binomial Radicals Expressions ** Multiply the coefficients and the radicands.** A. Multiply. 1. 2. 3.

Conjugates are expressions, like that differ only in the signs of the second terms. When a and b are rational numbers, the product of two radical conjugates is a rational number. B. Multiply each pair of conjugates. 1.2.

III. Rationalize the denominators. A. B.

Pre-AP – p. 378-380 11-49odd, 50-55, 57-63 odd rationalize both the denominator and numerator 65-68
