Hi,
(x^4+3x^3-4x^2)÷(x+4)
-4 1 3 -4
-4 4
1 -1 0
x^3 - x^2
Remainder = 0
(x + 4) a factor
Wish You the Best in your Studies.

   Theorem   (the remainder theorem)
   1. The remainder of division the polynomial    by the binomial    is equal to the value    of the polynomial.
   2. The binomial    divides the polynomial    if and only if the value of    is the root of the polynomial  ,  i.e.  .
   3. The binomial    factors the polynomial    if and only if the value of    is the root of the polynomial  ,  i.e.  .
