Factoring by grouping is like "undistributing" or unwrapping our polynomial. You pictured a baked potato too, huh? The simplest situation in which we can factor by grouping is when we have a four-term polynomial whose first two terms have their own common factor, and whose last two terms have their own common factor.

This is because we can rewrite the expression as follows: Then we can use grouping to factor as . For more on factoring quadratic trinomials like these using the grouping method, check out our next article.

Factoring - Grouping Objective: Factor polynomials with four terms using grouping. The ﬁrst 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.

Notice that, although 1 is the GCF for all four terms of the polynomial, the first 2 terms have a GCF of y and the last 2 terms have a GCF of 2. xy + y + 2x + 2 = x · y + 1 · y + 2 · x + 2 · 1 = y(x + 1) + 2(x + 1) = (x + 1)(y + 2) Factoring by Grouping Example I call it "factoring in pairs", but your book may refer to it as "factoring by grouping".

As the name suggests, factoring by grouping is simply the process of grouping terms with common factors before factoring. To factor a polynomial by grouping, here are the steps: Check whether the terms of the polynomial have the Greatest Common Factor (GCF).

Then click the button and select "Factor by grouping" to compare your answer to Mathway's. (Or skip the widget and continue with the lesson.) We are going to use a method known as the 'ac' method to factor these types of quadratic equations. This is a systematic method that employs factoring by grouping. It is always much easier to look at some example problems before reading generalized steps, but the steps go as follows.
