Question 169525
X TO THE SECOND POWER - X - 20
DIVIDED BY
X TO THE SECOND POWER - 14X +48
---------------------
{{{(x^2 - x - 20)/(x^2 - 14x + 48)}}}
={{{((x-5)*(x+4))/((x-6)*(x-8))}}}
There are no common factors, so it can't be reduced.  Attempts to divide it will only result in a remainder that is at least as complex as the original trinomials.
