Answer:
Explanation:
It all depends upon what the terms are. If each term of the 3 all have a variable you can factor out, then you'd do that first. For example, if your trinomial looks like this:
you would begin by factoring out the common x, reducing the third degree polynomial to a quadratic which can then be factored many ways.
If that is not the case, then you are factoring higher degree polynomials, and the way I always recommend to my students is the Rational Root Theorem and then synthetic division.
