Example
2. Use the "Horner
tableau" to find
for the polynomial
.
Solution 2.
The fifth degree polynomial is
.
When n=5 the Horner tableau is

Substitute the coefficients
and
into
the table and get

![[Graphics:../Images/HornerMod_gr_62.gif]](../Images/HornerMod_gr_62.gif)
We are done.
Aside. We can check
out the quotient and remainder. The last step above gives us the
coefficients
of
and
.
