factorization? by ariels

Type: Erratum
Correction text:
The term "factorization" is probably best not used for describing Horner's rule: saying
y = a_0 + x(a_1 + ...)
is hardly a factorization: it requires a (usually) nonzero
remainder a_0.
Perhaps say "rearrangement" or "equality"?

Sure it's a factorization. But not a factorization of y, a factorization of (a_1*x + a_2*x^2 + ...).
The entry says it makes use of "the factorization ...", but it doesn't say what it is of. In light of this, I'll accept the correction, and be less ambiguous. |
