Answer:

1

x

−

5

Explanation:

The key realization is that our denominator fits the difference of squares pattern

a

2

−

b

2

, which factors as

(

a

+

b

)

(

a

−

b

)

.

We can rewrite

x

2

−

25

as

(

x

+

5

)

(

x

−

5

)

, which allows us to rewrite our original expression as

x

+

5

(

x

+

5

)

(

x

−

5

)

The

x

+

5

terms on the top and bottom cancel, and we're left with

x

+

5

x

(

x

)
