I think you want to factor this expression which is a difference of squares
36x2 is the quantity (9x)2 and 100y6 is the quantity (10y3)2
we factor any difference of squares a2 - b2 into (a+b)(a-b)
so if you can determine what is a and what is b you're all set.
from what I said above, a = 9x and b = 10y3
Can you now write the two factors?
