Understanding Factorization by Grouping
Factorization by grouping is a process of breaking a polynomial into two or more polynomials with common factors. It is helpful in simplifying and organising equations and is used to solve advanced algebraic equations.
In this article, we will talk about the technique of factorization by grouping and the resulting expression when we factor 6×4 – 5×2 + 12×2 – 10
by grouping.
Explanation of the concept of Factorization by Grouping
Factorization by grouping is a technique used to factorise algebraic expressions by grouping terms that share common factors. This method is particularly useful when dealing with polynomials that have four or more terms.
The steps to factorise an expression using grouping are as follows:
- Identify pairs of terms that share common factors.
- Group the pairs together, creating two sets.
- Factor out the GCF (greatest common factor) from each set.
- Factor out the GCF from the resulting expression, if possible.
- Simplify the expression by combining like terms.
For example, factoring the expression 6×4 – 5×2 + 12×2 – 10 by grouping involves grouping the first two terms and the second two terms together, factoring out x2 from each set, and then factoring out 2 from the resulting expression. The simplified expression is then 2×2(3×2-2)+2(3×2-2), or (3×2-2)(2×2+1). Factoring by grouping can save time and effort when dealing with complex expressions.
How to recognize the need to factor by grouping
In algebra, factoring by grouping is a method used to simplify algebraic expressions by grouping terms with common factors. It is used when the algebraic expression cannot be factored using other methods such as factoring out a common factor or using the difference of squares formula.
To recognize the need to factor by grouping, look for an algebraic expression with four terms and pairs of terms that share a common factor. The pairs of terms need to be grouped together so that the common factors can be factored out.
For example, in the expression 6x^4 – 5x^2 + 12x^2 – 10
, we can group the first two terms and the last two terms, noticing that the common factor in the first pair of terms is 1x^2
and in the second pair of terms is 2
. Then factor out the common factor from each pair, giving you 1x^2(6x^2 – 5) + 2(6x^2 – 5)
. Notice that the resulting two terms are identical, so you can factor out the common factor (6x^2-5)
, leaving you with the final expression: (6x^2-5)(x^2+2)
.
Factoring by grouping is beneficial because it simplifies the algebraic expression and makes it easier to work with in future calculations. It is often used in calculus, trigonometry, and other advanced maths courses.
Why factoring by grouping can be advantageous compared to other methods
Factoring by grouping is advantageous compared to other methods of factorization because it makes the process quicker and more straightforward.
Let’s take the example of factoring 6×4 – 5×2 + 12×2 – 10 by grouping:
| Step 1: Group the terms with common factors. In this case, group the first two terms and the last two terms. |
| (6×4 – 5×2) + (12×2 – 10) |
| Step 2: Factor out the common factor from each group. |
| x2 (6×2 – 5) + 2(6×2 – 5) |
| Step 3: Notice that each group now has a common factor of (6×2 – 5), which can be factored out. |
| (6×2 – 5) (x2 + 2) |
By factoring the expression through grouping, we were able to simplify the process and arrive at the solution – (6×2 – 5) (x2 + 2) – quicker and more efficiently than other methods.
Pro Tip: Practice and familiarity with the technique of factoring by grouping can save you valuable time and reduce errors in more complex expressions.
