Learn how to add and subtract the square root of three different numbers

The video tutorial explains the process of adding radicals, emphasizing the need for common radicands, similar to adding like terms in polynomials. It highlights the difference between operations involving multiplication and addition, using examples like 2X plus 3X and 2X plus 3Y. The tutorial stresses that radicands must be the same to combine them in addition or subtraction, unlike multiplication or division. The video concludes with a demonstration of simplifying radicals to reach a final answer.

What is necessary for adding radicals together?

• Common radicands

• Common coefficients

• Common exponents

• Common bases

Why can't 2X and 3Y be added together?

• They are not like terms

• They have different coefficients

• They are both constants

• They are both variables

What should be done before adding or subtracting radicals?

• Simplify the radicals

• Divide the radicals

• Multiply the radicals

• Square the radicals

In the example provided, what is the final result of the operation?

• 6 times square root of 2

• 2 times square root of 3

• 3 times square root of 2

• 0

What happens when you subtract 2 times square root of 3 from itself?

• It becomes 0

• It becomes 2

• It becomes 3

• It becomes 1
