Learn how to factor four term polynomials by grouping or without grouping using algebraic identities and substitution methods. See examples, steps and explanations for each method.
A term is a combination of a constant and variables. Factoring is the reverse of multiplication because it expresses the polynomial as a product of two or more polynomials. A polynomial of four terms, known as a quadrinomial, can be factored by grouping it into two binomials, which are polynomials of two terms.
When a polynomial has four or more terms, the easiest way to factor it is to use grouping. In this method, you look at only two terms at a time to see if any techniques become apparent. For example, you may see a Greatest Common Factor (GCF) in two terms, or you may recognize a trinomial as a perfect square.
Learn how to factor polynomials by grouping. A polynomial is an expression of the form ax^n + bx^ (n-1) + . . . + k, where a, b, and k are constants and the exponents are positive integers. To ...
Learn how to Factor using the factoring by Grouping method in this free math video tutorial by Mario's Math Tutoring.0:05 How to Know When to Try the Factori...
Finally, group the terms to form pairs, factor out each pair, and factor out the shared parentheses. To learn how to factor polynomials by grouping, scroll down!
To factor by grouping, look at smaller groups of terms (2 or 3 terms) within a polynomial. Next, factor out the GCF from each group. Then, compare the factored groups to see if there are any common factors. A group of 3 terms may factor easily as a trinomial.
Easy to follow tutorial on how to factor by grouping with 4 terms. We will do several examples of factoring by grouping, including a shortcut and an example...
There isn’t a common factor between all four terms, so we will group the terms into pairs that will enable us to find a GCF for them. For example, we wouldn’t want to group a2 and 15 a 2 and 15 because they don’t share a common factor. Note how the a and 5 become a binomial sum, and the other factor. This is probably the most confusing part of factoring by grouping.
Learn how to factor polynomials with 2, 3, 4, or more terms with rules, methods, steps, examples, and diagrams.
Additionally, factoring by grouping is a technique that allows us to factor a polynomial whose terms don't all share a GCF. In the following example, we will introduce you to the technique. Remember, one of the main reasons to factor is because it will help solve polynomial equations.
The way to factor a four-term polynomial like this is to apply Rational Root Theorem along with synthetic division or substitution to determine whether a rational root works for the polynomial or not. Here is how Rational Root Theorem works.
The process of factoring a polynomial with four terms is called factor by grouping. With all factoring problems, the first thing you need to find is the greatest common factor, a process that is easy with binomials and trinomials but can be difficult with four terms, which is where grouping comes in handy.

Factor the following polynomials without grouping : Example 1 : x 3 - 2x 2 - x + 2 Solution : Let p (x) = x 3 - 2x 2 - x + 2. Substitute x = -1. p (-1) = (-1) 3 - 2 ...
Note: Factoring by grouping is one way to factor a polynomial. This tutorial shows you how to take a polynomial and factor it into the product of two binomials. Then, check your answer by FOILing the binomials back together!
Step 4: Factor out the common factor - (x + 2) (x 2 − 3). Step 5: The polynomial is now factored as (x + 2) (x 2 − 3). Factoring polynomials with four or more terms requires practice and patience, but mastering this skill can greatly simplify algebraic expressions and equations.
