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.
