This time the polynomial is of order 5 and as you can
see from the graph all the factors are real. Here are
first estimates,
= −2.8, −2.4, −0.6, 0.7, 1.6
The fx keystrokes are,
CQ(X)^5$+3.5J(X)^4
$p2.5J(X)q(x )p12.5
3
J(X)d+1.5J(X)+5
r
X? z2.8=n
Only a reasonable estimate, needs some tweaking to
get a better result.
r
X? z2.4=n
A slightly better result than the previous one, still too
big.
