Factor Trees. One method for producing the prime factorization of a natural number is to use what is called a factor tree. The first step in making a factor tree is to find a pair of factors whose product is the number that we are factoring. These two factors are the first branching in the factor tree.
Sep 06, 2019 · To factor trinomials, make sure you know FOIL (First, Outside, Inside, Last) multiplication and how to factor. Write a space for the answer in FOIL form and fill in the First terms. Next, use factoring to guess at the Last terms. To factor, find two numbers that multiply to form the Last term. 3. Check each factor to see if you can factor it further. If so, then we factor again. The concept behind step 3 above, is that of factoring completely. This means, we cannot leave any factor that could be factored again. We saw some of this in the last section, but we will see much more of it in this section.
