Given:
The equation is
To find:
The value of x.
Solution:
We have,
It can be written as
Cancel out the common factors.
Therefore, the value of x is -3.
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.
