r

X? z0.6=n

Far too big, need more tweaking to get closer to the

root value.
r

X? 0.7=n

A good result, very close to the actual root value.

r

X? 1.6=n

A really poor estimate.

As a worthwhile exercise work on each of the factor

estimates for the four polynomials using trial and

error to improve them and get closer to the actual
factors.
