|
This includesradicals that contain variable factors, but continues the simplification of various terms in a sum or difference so that possible like terms can be added orsubtracted.

|
This shows how to simplify the parts of an addition of radicals and then add or subtract the like terms.
|
|
|
This shows how to simplify square roots in an additon problem so that hopefully you get like terms and con simplify further.
|
|
|
Shows how to separate out the persct square so they can become whole numbers or expression leaving the remaining factors under the square root.
|
|
|
Demonstrats how to free all perfect squar in a radical expression so they are whole.
|
|
|
Shows how to create squares under the square root so that both the exponent of two and the square root will elminiate each other.
