The general advice is if you can't see right away that you should use one option over another, then just choose one and work with it until you successfully factor, or exhaust all possibilities of the factors.

f(b) f(a) > 0 > f(b) then there is at least one number c, a < c < b. such that f(c) = 0. That is, f(x) has a root in. = ax () loga(y) = x which is merely a statement that ax and loga(y) are in.

Factoring Practice I. Greatest Common Factor (GCF) Find the GCF of the numbers. 18, 30 6 = GCF

Since this is a binomial, and since the two terms are being added together, I am looking for terms that are both perfect cubes in order to factor using the Sum of Cubes formula.

Factoring linears To completely factor a linear polynomial, just factor out its leading coe -cient: ax + b = + a⌘ b For example, to completely factor 2x + 6, write it as the product 2(x + 3).

Complex factoring problems can be solved using the chart as a general guide and applying the techniques that will be discussed below. As with any concept, the way to get good at factoring is to …

In matrix terms = x + f + u: Here, f is the common underlying factor (overall ability) that explains all three scores.
