Simplify Expressions A Step-by-Step Guide
In the realm of mathematics, simplification reigns supreme as a fundamental technique that allows us to unravel the intricacies of complex expressions and equations. At its heart, simplification is the art of transforming a mathematical expression into a more manageable and equivalent form, all while preserving its inherent value and meaning. This transformation often involves a delicate dance of combining like terms, skillfully applying the distributive property, and strategically employing the order of operations.
At the heart of simplification lies the combination of like terms, a process akin to gathering kindred spirits together. Like terms, those mathematical entities that share the same variable raised to the same power, are the building blocks of simplification. Imagine them as Lego bricks of the same shape and size, ready to be assembled into a larger structure. For instance, in the expression 3x + 5x - 2x
, the terms 3x
, 5x
, and -2x
are like terms, all sporting the variable x
raised to the power of 1. By combining these like terms, we can condense the expression into a more concise 6x
, revealing the underlying simplicity.
The distributive property, a mathematical gem, plays a pivotal role in simplification, particularly when dealing with expressions enclosed in parentheses. This property empowers us to gracefully navigate parentheses by multiplying a term outside the parentheses with each term nestled inside. Picture it as a friendly messenger, distributing the external factor to each internal recipient. Consider the expression 2(x + 3)
. The distributive property dictates that we multiply 2
by both x
and 3
, yielding 2x + 6
, a simplified and expanded form. This property is instrumental in unraveling expressions and preparing them for further simplification.
The order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction), acts as a mathematical compass, guiding us through the simplification process with unwavering precision. This established hierarchy ensures that we perform operations in the correct sequence, preventing mathematical chaos. Parentheses take precedence, followed by exponents, then multiplication and division (from left to right), and finally, addition and subtraction (also from left to right). Embracing the order of operations is crucial for achieving accurate and consistent simplification results.
Demystifying the Expression:
Let's embark on a journey to simplify the expression $3(4x - 5y) + 2y$
, a mathematical puzzle that awaits our skillful unraveling. This expression presents a captivating blend of parentheses, variables, and coefficients, offering a perfect canvas for us to apply the principles of simplification.
Our first move, guided by the order of operations, is to conquer the parentheses. The distributive property comes to our aid, allowing us to multiply the term outside the parentheses, 3
, with each term inside, $4x$
and $-5y$
. This elegant maneuver transforms the expression into $12x - 15y + 2y$
, effectively liberating the terms from their parental confines.
With the parentheses now dissolved, our attention shifts to the combination of like terms. We scan the expression for terms that share the same variable raised to the same power. In this case, we spot $-15y$
and $2y$
, both adorned with the variable y
raised to the power of 1. These like terms beckon to be united.
We carefully combine $-15y$
and $2y$
, adding their coefficients together. The result, $-13y$
, replaces the original terms, streamlining the expression. Our simplified expression now stands as $12x - 13y$
, a testament to the power of simplification.
This final expression, $12x - 13y$
, is the simplified equivalent of the original $3(4x - 5y) + 2y$
. We have successfully navigated the expression, applying the distributive property and combining like terms to arrive at a more concise and manageable form. This simplified expression retains the same mathematical value as the original, yet it presents itself in a clearer and more accessible light.
Step-by-Step Simplification
To solidify our understanding, let's recap the simplification process step-by-step:
- Distribute: Apply the distributive property to eliminate parentheses:
$3(4x - 5y) + 2y$ becomes
`. - Combine Like Terms: Identify and combine like terms:
$-15y + 2y$
becomes$-13y$
. - Simplified Expression: The simplified expression is
$12x - 13y$
.
The Significance of Simplification
Simplification is not merely a mathematical exercise; it is a cornerstone of problem-solving, offering a multitude of benefits that extend far beyond the classroom. It empowers us to:
- Enhance Clarity: Simplified expressions are easier to comprehend and interpret. They strip away unnecessary complexity, revealing the underlying structure and relationships between variables and constants.
