Factorization Techniques Simplified: A Step-by-Step Guide

Factorization is a fundamental concept in algebra that involves breaking down an expression into a product of simpler expressions. This guide will walk you through the process of factorizing the expression 7a14 - 2b - ab. By understanding and employing the correct factorization techniques, you can simplify complex expressions into more manageable forms.

Understanding the Expression

The expression we're dealing with is 7a14 - 2b - ab. At first glance, it may seem complex and intimidating, but by breaking it down, we can find the common factors and simplify it effectively.

Step-by-Step Factorization

Step 1: Grouping Terms

First, let's group the terms in a way that highlights any common factors. Notice that the first term, 7a14, is a multiple of 7, while the second and third terms, -2b and -ab, have a common factor of b when rearranged:

7a14 - 2b - ab 7a14 - ab - 2b 7a14 - b(a 2)

Step 2: Factoring Out Common Factors

Let's start by factoring out the common factor of 7 from the first term:

7a14 - b(a 2)

However, this step doesn't yield a simpler form. Let's re-evaluate our approach by grouping differently:

7a14 - ab - 2b

Step 3: Factoring Further

Upon closer inspection, we notice that the last two terms, -ab and -2b, have a common factor of b if rearranged properly:

7a14 - b(a 2) 7a14 - ab - 2b 7a14 - b(a 2)

Now, let's factor out b from -ab - 2b:

7a14 - b(a 2)

However, this still doesn't produce the simplest form. Let's re-examine the original expression:

7a14 - ab - 2b

We can rearrange it to 7a14 - b(a 2), but this isn't the most straightforward path. Instead, let's look at the term a14 and see if we can simplify it:

7a14 - b(a 2)

To simplify, we should focus on the 7a14 term:

7a14 - ab - 2b

By rearranging, we get:

a14 - b

Now, we factor out the common factor:

a27 - b

Conclusion

After careful analysis, the factorized form of the expression 7a14 - 2b - ab is a27 - b. This simplified form is more manageable and easier to understand.
