Factor the numerator and denominator expressions, and then simplify.


Example 1:

Simplify.
x2 - 9x + 18
x - 3
 

 
x2 - 9x + 18
x - 3
=
(x - 3)(x - 6)
x - 3
=
(x - 3)(x - 6)
x - 3
= x - 6


Example 2:

Simplify.
x2 - 3x - 10
x2 - 9x + 20
 

 
x2 - 3x - 10
x2 - 9x + 20
=
(x - 5)(x + 2)
(x - 4)(x - 5)
=
(x - 5)(x + 2)
(x - 4)(x - 5)
=
x + 2
x - 4
