Having learned about multiplying binomials in the above way makes the process of factoring simple trinomials easier for students to discover.

As there exists a trinomial or pentanomial basis for GF([2.sup.n]) having at most four elements of trace one for each n e [2, 10000] [4], the polynomial g(x) with less number of trace-one elements that appeared in its polynomial basis is acceptable.
Thus, limiting the weight of criterion bearers [P.sub.i] by the first and the second powers and assuming the condition that, in formula (12), the expression of the numerator and denominator with respect to [P.sub.i] will be a square trinomial, we will obtain the following version of the coefficient GRS:
She gives a useful example related to algebra and the factoring of trinomials (74-75).
Students do not encounter insurmountable difficulties in this topic in which all their cognitive efforts are concentrated on either factoring trinomials or using quadratic formulas.
Thus people often use known primitive trinomials to specify SRG recursions.
A brief comment is in order on my use of the names Procambarus (Ortmannicus) acutus (Girard) and Procambarus (Ortmannicus) cuevachicae (Hobbs), instead of the more established trinomials P.
For ease of communication, and because the subspecies recognized by Stebbins (1949) are "candidate" species, we refer to subsets of our 48 population sample by trinomials. It is difficult to segregate picta from oregonensis on morphological grounds, and we decided to identify only one population as picta.
They should say, "Eleven-year-olds should be able to multiply trinomials." If we want to use a computer to teach that, or teacher-created materials or the Houghton-Mifflin text in math, that's a decision a specific teacher should be making in working with a specific kid, not the state of Florida.
