binomial radical expressions , rationalize , multiply

🔎 In this video, we learn how to simplify binomial radical expressions using multiplication and division. We start by distributing the root symbol to each term inside the parentheses and then multiply the like terms under the root symbol. We also learn how to rationalize the denominator by multiplying by a convenient form of the number one.

🔢 Math concepts covered binomial radical expressions, square roots, multiplication, distribution, rationalizing the denominator, and FOILing.

1️⃣ How do you simplify binomial radical expressions using multiplication and division?
Answer Distribute the root symbol to each term inside the parentheses and then multiply the like terms under the root symbol.

2️⃣ What is rationalizing the denominator?
Answer Rationalizing the denominator means getting rid of the square root symbol on the bottom of a fraction.

3️⃣ How do you rationalize the denominator?
Answer Multiply by a convenient form of the number one, usually the conjugate of the denominator.

4️⃣ What is FOILing?
Answer FOILing is a method used to multiply two binomials.

5️⃣ How do you multiply radical expressions?
Answer Multiply the coefficients outside the root symbol and then multiply the like terms inside the root symbol.

6️⃣ How do you divide radical expressions?
Answer Divide the coefficients outside the root symbol and then divide the like terms inside the root symbol.

7️⃣ What is a perfect square?
Answer A perfect square is a number that is the square of an integer, for example, 4, 9, 16.
