Solution 11863: The factor() Function Algorithm on the TI-89 Family, TI-92 Family, and Voyage™ 200 Graphing Calculators.
What is the factor() function algorithm on the TI-89 family, TI-92 family, and the Voyage 200?
The factor() function returns the rational number
factored into primes and a residual having prime factors that exceed
65521. The methods include the well-known factorizations of binomials
and quadratics, together with methods described by Geddes, Czapor and
Labahn, "Algorithms for Computer Algebra", Kluwer Academic Publishers,
Boston, 1992.
Laguerre's method is used
for approximate polynomial factorization. (Press et. al: "Numerical
Recipes" Cambridge University Press, 1986.)
