Are you learning from these questions or are we just doing your homework for you?
Presuming we have a polynomial divided by a fraction:
(x² + 6x + 8) / [(x² - 4) / (x² - 16)]
The first thing I would do is turn the division of the fraction into the multiplication of the reciprocal:
(x² + 6x + 8) * [(x² - 16) / (x² - 4)]
Now factor what you can:
(x + 4)(x + 2) (x + 4)(x - 4) / [(x + 2)(x - 2)]
Then cancel out the common factors in the numerator and denominator (x + 2):
(x + 4)(x + 4)(x - 4) / (x - 2)
Then simplify to get your final result:
(x + 4)(x² - 16) / (x - 2)
(x³ + 4x² - 16x - 64) / (x - 2)
