Step-by-step explanation:
When fractions are adding, we can't combine them unless they have a common denominator.
To make
1
1
+
x
+
1
−
x
x
have the same denominator, we need to "give"
1
1
+
x
an
x
and
1
−
x
x
an
(
1
+
x
)
.
We'll "give" the fractions those denominators by multiplying both top and bottom that value. We do that because
x
x
and
1
−
x
1
−
x
are both equal to
1
, and we can multiply anything by
1
without changing it's actual value.

Lets factor out that negative
−
1
(
x
2
−
x
−
1
)
x
2
+
x
An now we can factor the denominator
−
1
(
x
2
−
x
−
1
)
(
x
)
(
x
+
1
)
x
2
−
x
−
1
can't be factored, so this is as simplified as we can get
