I didn't get all the part with the tiles, but here's the general answer:
given a polynomial

we have that
is a factor of
if and only if k is a root of
, i.e. if

So, given the polynomial

We can check if
is a factor by evaluating
:

So,
is not a factor.
Similarly, we can evaluate
to check if
are factors:

So, only
is a factor of 
Answer:
(3,12)
Step-by-step explanation:
you would put the 12 as y then 3×3=9+6=15 and 12 doesn't equal 15
Answer:
36
Step-by-step explanation:
First you would solve what's in the parenthesis because the Order of Pemdas.
Second you would multiply the answer of what's in the parenthesis which is 3 to 12.
Third you would get the answer which is 36!
Simplify the radical by breaking down the radicand up into a product of known factors.
