a) 12x³ + 4x²
--------------------
2x²
= 2x² ( 6x + 2)
-----------------------
2x²
= 6x + 2
b) x² + 5x + 6
----------------------
x + 2
= ( x + 2)( x + 3)
------------------------
x + 2
= x + 3
c) 2x² - x - 10
----------------------
x + 2
= (2x - 5)( x + 2)
------------------------
x + 2
= 2x - 5
d) 2x³ + 7x² - 14x - 40
--------------------------------
2x - 5
= ( 2x - 5)( x² + 6x + 8)
---------------------------------
2x - 5
= x² + 6x + 8
e) 3x³ - 4x² - 5x + 6
------------------------------
x + 2
= ( x + 2) ( 3x² - 10x ) + ( 15x + 6)
-----------------------------------------------
x + 2
= ( 3x² - 10x ) + ( 15x + 6)
= 3x² + 5x + 6
