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
