What is a perfect square and what is "square root" ? You may give examples to show understanding.
A perfect square is the PRODUCT of 2 factors that are WHOLE NUMBERS.
ex. 3 * 3 = 9 , 9 is the perfect sqaure
Square Root is the "answer" or the "FACTOR" that you multiply to itself.
ex. The Square Root of 9 is 3.
or Three is the Square Root of 9.

8 = X / 2
Explain how to "check your solution."
GEMDAS backwards
multiply both sides by 2
16 = X
Plug 16 back in for the "X"
16 / 2 = 8
