Working with only the numerator: (factoring out 32012 )
32012·33 + 32012·32 + 32012·3 = 32012·(33 + 32 + 3) = 32012·(27 + 9 + 3) = 32012·(39)
Working with only the denominator:
32012·32 - 32012·31 - 32012 = 32012·(32 - 31 - 1) = 32012·(9 - 3 - 1) = 32012·(5)
Combining: 32012·(39) / 32012·(5) = 39 / 5
