We are technically FOILing this out... with a power of 3.
(x+y)(x+y)(x+y)
So we can first factor out the first two "x+y"s.
, multiplied by the last "x+y".
Coefficients are the number that comes in front of a variable.
In this case, 1 comes in front of
, 3 comes in front of 
, 3 comes in front of 
, and 1 comes in front of 
.
Thus: 1, 3, 3, 1.
