Simplify: { (2v - 4)(2v + 4)$}$
Introduction
When it comes to simplifying algebraic expressions, there are several techniques and strategies that can be employed to make the process easier and more efficient. One of the most common techniques is the use of the distributive property, which allows us to expand and simplify expressions by multiplying each term in one expression by each term in the other expression. In this article, we will explore how to simplify the expression {(2v - 4)(2v + 4)$}$ using the distributive property.
Understanding the Distributive Property
The distributive property is a fundamental concept in algebra that allows us to expand and simplify expressions by multiplying each term in one expression by each term in the other expression. The distributive property can be written as:
a(b + c) = ab + ac
This means that we can multiply each term in the expression (b + c) by the term a, and then combine the results.
Applying the Distributive Property to the Expression
To simplify the expression {(2v - 4)(2v + 4)$}$, we can use the distributive property to expand and simplify the expression. We will multiply each term in the first expression (2v - 4) by each term in the second expression (2v + 4).
{(2v - 4)(2v + 4)$}$ = (2v)(2v) + (2v)(4) - (4)(2v) - (4)(4)
Simplifying the Expression
Now that we have expanded the expression using the distributive property, we can simplify it by combining like terms. We will multiply each term in the expression and then combine the results.
{(2v)(2v) + (2v)(4) - (4)(2v) - (4)(4)$}$ = 4v^2 + 8v - 8v - 16
Combining Like Terms
Now that we have simplified the expression, we can combine like terms to get the final result.
4v^2 + 8v - 8v - 16 = 4v^2 - 16
Conclusion
In this article, we explored how to simplify the expression {(2v - 4)(2v + 4)$}$ using the distributive property. We applied the distributive property to expand and simplify the expression, and then combined like terms to get the final result. By following these steps, we can simplify complex algebraic expressions and make them easier to work with.
