I guess this will be good example of how to do it
(x+6)(x-6) would be the factored form
Tiles = greek philosopher who contributed to 5 theorems of elementry geometry
Elucid = regarded as the father of geometry
Hippocrates = a mathematician who compiled basic geometric facts, or elements, into a textbook
Pythagoras = greek geometrer who has a theorem named after him
Im pretty sure it would be B) 100
The answer to this is x = 5.
