Introduction to factoring by grouping
Factoring by grouping is a technique used in algebra to find the factors of a polynomial. It involves grouping terms with common factors and factoring out these common factors. To understand factoring by grouping, let’s take the example of x³ – 12x² – 2x + 24.
Group the first two terms (x³ – 12x²) and factor out the common factor (x²). This will give you x²(x – 12).
Group the last two terms (-2x + 24) and factor out the common factor (-2). This will give you -2(x – 12).
Notice that both groups have (x – 12) as a common factor. Combine the two groups and factor out (x – 12) to get (x² – 2)(x – 12).
Factoring by grouping may seem daunting initially, but it can become an essential tool in solving more complex algebraic equations with practice.
Identifying the Polynomial and Its Degree
A polynomial is a sum of variables raised to the power of non-negative integers in mathematics. For example, in the polynomial x3 – 12×2 – 2x + 24, the variables are ‘x’ and the polynomial terms can be identifed as x3, -12×2, -2x and 24. It also has a degree of 3, as the highest power of the variable is 3. The aim in factoring polynomials is to identify its factors. Let’s look at one way to determine the factors of x3 – 12×2 – 2x + 24 by grouping.
Understanding degrees of polynomials
In algebra, a polynomial is an expression consisting of variables and coefficients, and having one or more terms. The degree of a polynomial is the highest power (exponent) of the variable in the expression.
For example, the polynomial expression 3×2 + 2x – 1 has a degree of 2 because the highest exponent of x is 2.
To determine the degree of a polynomial, identify the term with the highest exponent of the variable in the expression.
In the polynomial x3 – 2×2 + 5x – 7, the term with the highest exponent is x3, so the polynomial degree is 3.
Understanding the degree of a polynomial is important in algebra because it can help you determine the complexity of the solution and the number of solutions that exist.
Factoring polynomials is one way to determine the factors of a polynomial expression, such as x3 – 12×2 – 2x + 24. Grouping similar terms can simplify the expression and make it easier to factor. Pro Tip: Practice identifying the degree of polynomials until you are comfortable with the concept.
Identifying the degree of x3 – 12×2 – 2x + 24
The given expression, x3 – 12×2 – 2x + 24, is a polynomial with four terms and a degree of 3.
To identify the degree of a polynomial, we need to find the term with the highest power of the variable. In this case, the highest power of x is 3, which means that the degree of the polynomial is 3.
To factor this polynomial using grouping, we can first group the first two terms and the last two terms:
(x3 – 12×2) + (-2x + 24)
Next, we can factor out the greatest common factor from each group:
x2(x – 12) – 2(x – 12)
Now, we can see that we have a common binomial factor of (x – 12), which we can factor out:
(x2 – 2)(x – 12)
Therefore, the factors of x3 – 12×2 – 2x + 24 are (x2 – 2) and (x – 12).
Pro tip: Identifying the degree of a polynomial is crucial in determining its end behavior, which can help us understand the shape of its graph. Factoring polynomials can also help solve equations and simplify algebraic expressions.
Exploring common factors
To factorize a polynomial, the first step is to determine the polynomial’s degree and identify the common factor(s) that can be removed. This technique can be helpful to factorize more complex polynomials.
Let’s take the example of x3 – 12×2 – 2x + 24, to determine its factors by grouping. We will take the common factor from the first two terms (x2) and the last two (-2). By doing so, we get:
x2(x – 12) – 2(x -12)
You can see that both terms have a common factor – (x – 12). So, we can write:
(x – 12)(x2 – 2)
Therefore, the factors of x3 – 12×2 – 2x + 24 are (x – 12) and (x2 – 2).
We can factorize more complex polynomials with higher degrees and multiple terms using this technique.
Pro Tip: Practice factoring simpler polynomials before moving on to more complex ones. It will help you to understand and master the concept of factoring.

(x³ – 12x²) – (2x – 24)
2. Factor out the common factors from each group:
x²(x – 12) – 2(x – 12)
3. Note that the remaining terms have a common factor of (x – 12):
(x² – 2)(x – 12)
4. Thus, x³ – 12x² – 2x + 24 can be factored as (x² – 2)(x – 12) through factoring by grouping.
Factoring by grouping may initially seem complicated, but it is a useful method for simplifying complex polynomials.
Simplifying the grouping
Factoring by grouping is a technique used to factor polynomials that involve four terms. This technique simplifies the grouping by grouping the polynomials into two groups of two terms. Here are the steps to factor the polynomial x3 – 12×2 – 2x + 24 by grouping:
Step Process
1 Group the first two terms and factor out the greatest common factor. x²(x – 12).
2 Group the last two terms and factor out the greatest common factor. -2(x – 12).
3 Combine the two factored groups. x²(x – 12) – 2(x – 12).
4 Factor out the common factor (x – 12) from the expression. (x – 12)(x² – 2).
By simplifying the grouping, we can easily determine the given polynomial factors, which are (x – 12) and (x² – 2).
Pro tip: Practice makes perfect when it comes to factoring by grouping. The more polynomials you factor, the easier it becomes to identify the right grouping.

Therefore, the factors of the polynomial x3 – 12×2 – 2x + 24 are (x – 12)(x2 – 2). By factoring the expression, we can simplify it and find the equation’s roots, or solutions, more easily.
Pro Tip: Factoring by Grouping is a helpful technique for factorizing polynomial expressions that have four terms. Remember to group the terms carefully and look for the GCF of each pair before factoring out the common binomial factor.
