Exploring the Expression (3n - 1)(2n^2 + 4n + 4)
This article will delve into the expression (3n - 1)(2n^2 + 4n + 4), exploring its properties and how it can be manipulated.
Expanding the Expression
The expression is currently in factored form. To understand its behavior, we can expand it using the distributive property:
(3n - 1)(2n^2 + 4n + 4) = 3n(2n^2 + 4n + 4) - 1(2n^2 + 4n + 4)
Expanding further:
(3n - 1)(2n^2 + 4n + 4) = 6n^3 + 12n^2 + 12n - 2n^2 - 4n - 4
Combining like terms:
(3n - 1)(2n^2 + 4n + 4) = 6n^3 + 10n^2 + 8n - 4
Analyzing the Expanded Form
The expanded form reveals a cubic polynomial with the following properties:
- Leading coefficient: 6
- Degree: 3 (highest power of n)
- Constant term: -4
This polynomial can be used to:
- Find its roots: Solving the equation 6n^3 + 10n^2 + 8n - 4 = 0 will give us the values of n where the expression equals zero.
- Graph the function: Plotting the points (n, 6n^3 + 10n^2 + 8n - 4) will provide a visual representation of the function's behavior.
Further Exploration
Beyond basic expansion, we can investigate:
- Factoring the polynomial: While the initial factored form provides some insight, further factoring may reveal additional properties.
- Applications in other contexts: The expression could potentially be used in areas like physics, engineering, or computer science depending on the specific problem.
