Question 914979
<pre>
The other tutor made a mistake.

We'll see what it should be.  But first of all you should not write 

2x^4 - 5x^3 + 7x^2 - 3x +1/ x - 3

because you must indicate with parentheses where every numerator 
and denominator begins and ends.  You use a "{" to show where they
begin and a ")" to show where they end.  IOW, you should have

(2x^4 - 5x^3 + 7x^2 - 3x +1)/(x - 3)

Without the parentheses the only things divided are the 1 and the x.
So in the future be sure to use parentheses to show where numerators
and denominators begin and end.


3 | 2 -5  7 -3  1
  |<u>    6  3 30 81</u>
    2  1 10 27 82

No, it's 2,1,10,27, and 82.  The answer to the division is {{{2x^3+1x^2+10x+27+82/(x-3)}}}
