Factoring by Grouping . If a four-term polynomial is present, and there is no GCF shared by all four terms, the terms can be grouped into pairs that have a GCF. This method is called factoring by grouping. Example 2: Factor the following expression using the grouping method. 10abx −8ax + 15bx −12x. Step 1: Check for a GCF.

Factoring - Grouping Objective: Factor polynomials with four terms using grouping. The ο¬rst thing we will always do when factoring is try to factor out a GCF. This GCF is often a monomial like in the problem 5xy + 10xz the GCF is the mono-mial 5x, so we would have 5x(y + 2z). However, a GCF does not have to be a monomial, it could be a binomial.

Here are the steps we can use for the grouping method. Factoring a 4-term Polynomial by Grouping 1. Arrange the terms so that the first two have a common factor and the last two have a common factor. 2. For each pair, factor out the GCF. 3. If step 2 produces a common binomial factor, factor it out.

Factoring some Trinomials by Grouping We will apply this technique to quadratic expressions. The following examples illustrate the steps: Example 1 To factor x2+3x+2x+6 by grouping, we note that the terms x2 and 3x have a common factor, namely x. Also the terms 2x and 6 have a common factor, namely 2. Therefore we put parenthesis around x2 +3x ...

Steps in factoring by grouping: 1. Determine if there is a GCF common to all four terms. If there is one then begin by factoring out this GCF. 2. Arrange the four terms so that the first two terms and the last two terms have common factors. 3. If the coefficient of the third term is negative, factor out a negative coefficient from the
