Find all roots of the polynomial
F(X)= x^3-x^2+16x-16.
F(1)=1-1+16-16=0
HENCE X-1 IS A FACTOR.DIVIDING..WITH X-1
1...|..1.....-1......16......-16
....|..0......1.......0.......16
------------------------------------
.......1......0.......16.......0
X^2-16 IS THE QUOTIENT
=(X+4)(X-4)
HENCE
F(X)=(X-1)(X+4)(X-4)
