Question 172562
Simplify:
{{{(t^4-t^3-14t^2+7t-4)/(t-4)}}}
Well, no wonder you're having trouble...the numerator is not factorable, and if you divide the numerator by the denominator, you get:
{{{t^3+3t^2-2t-1}}} and a remainder of {{{-8}}} so you can see that {{{t-4}}} is not a factor of {{{t^4-t^3-14^2t+7t-4}}} so I would have to conclude that the given fraction is already simplified.
