(
a
+
b
)
(
a
+
b
)
=
a
2
+

a
b
+
b

Substituting
x
for
a
and
y
for
b
gives:
(
x

(
x

y
)
=
x

Another way to show this is the correct answer is as follows:
To multiply these two terms you multiply each individual term in the left parenthesis by each individual term in the right parenthesis.

(
x
×
y
)
+
(
y
×
x
)
+
(
y
×
y
)
x

x
y
+
x
y
+
y
