For the number 1, there is only 1 pair of factors, eliminating any choice. Thus, the 1s can be inserted on the left side of each set of parentheses. Finally, a pair of factors of 16 must be chosen.
This is a matter of trial and error. To make sure all pairs are considered, start using factors at the top of the list then check each pair below it, in order. We place the factors on the right side of each set of parentheses. Note that the resulting trinomial is not the same as the one we started with, so this is the incorrect pair of factors of Try the next pair:.
Since the result here is eqivalent to the original, the correct pair of factors of 16 has been chosen. Additionally, the answer to the problem is. Only one of the three terms is negative. As a result, a minus sign should not be factored out as in the previous example. This expression will be factored much like the expression we just simplified above, but we will need to work with the minus sign as we build two sets of parentheses.
Now on the left of each set of parentheses, write all of the variables from the first term with half the exponent.
The first term is s 2 , after dividing its exponent by two, we place s on the left of each set of parentheses. The last term in the trinomial does not have any variables, so we do not need to carry any variables into the parentheses as a result. The coefficients are 1 and 6. Now write all pairs of factors of 1 in a vertical column and write all pairs of factors of 6 in another vertical column. For the number 1, there is only one pair of factors, eliminating any choice. Thus the 1s can be inserted on the left side of each set of parentheses.
Now a pair of factors of 6 must be chosen. To make sure all pairs are considered, check each pair of factors starting with the pair on the top of the list and working toward the bottom of the list. The problem below is similar to the last problem, but it has two negative signs in the expression. Write all of the variables from the first term with half the exponent in the front of each set of parentheses. Some worked example problems that point out many common errors students make when solving them.

A quadratic equation in general is defined as: We use an extension of factoring by grouping called the AC method.
Multiply together AC and list the factors of AC. Find a pair that adds to B. If you cannot find such a pair then the trinomial does not factor prime.
